Alex in particular was amazing and we felt very looked after, he really wanted us to relax so that's exactly what we did! We booked in for the Hippocratic Elixir treatment and it was 2 hours of pure bliss, would highly recommend! Food was great, but would recommend trying some of the local restaurants in town to mix things up - the staff will be able to recommend places.

Kos Town
The beachfront Lango Design Hotel & Spa, Adults Only offers accommodation in Kos Town. The hotel has a seasonal outdoor pool and a private beach area, and guests can enjoy a meal at the restaurant. Free WiFi is offered throughout the property. My husband and I stayed at Lango Design Hotel & Spa in Kos from July 7th to July 9th, booking through Booking.com, and it was truly one of the best vacation experiences we’ve ever had. The hotel is perfectly located in the Lambi Beach area, just a short 10-minute drive from the Ferry Port and literally steps away from the sea—separated only by a quiet road. We arranged our transfer through the hotel, and the warm and friendly front desk team greeted us with big smiles. To our delight, they surprised us with a complimentary upgrade to Room 105—the only room with a private pool and direct sea view. The room was absolutely beautiful, and the private pool was a lifesaver during the hot days we spent on the island. We also enjoyed relaxing on the balcony overlooking the sparkling sea—simply magical. One of the highlights of our stay was dining at Koan, the hotel’s Michelin-starred restaurant for 2025. We had an incredible dinner with live music, exceptional service, and delicious fusion seafood mezes alongside unique and flavorful dishes. The restaurant’s atmosphere, combined with the staff’s warmth, made it an unforgettable evening. Special thanks to Alexandra, the restaurant manager, who was outstanding—always smiling, polite, and full of great recommendations. The hotel’s breakfast buffet was equally impressive, with an incredible variety that catered to every taste and dietary need. From cheeses, charcuterie, and traditional Greek specialties to niche products like thyme honey, locust tree honey, and chestnut honey—it was beyond expectations. They even offered almond milk cappuccinos, kefir, fresh fruit, and healthy oatmeal options. The attention to guests’ allergies and dietary preferences was impeccable. We also enjoyed tasting local Kos wines—affordable and delicious—and spent time at the hotel’s beautifully designed spa and public pool area. The entire hotel is adults-only, which added to the serene and sophisticated atmosphere.

Such an amazing experience we had at KOIA! A beautiful complex that offers serenity and relaxation for couples. Stunning views, both from our roomand from the main pool area. Our suite was spacious and always clean. Staff was amazing, trying hard to make our stay as enjoyable as possible. Food was also great; interesting dinner menu and very fresh breakfast.
Beautiful design and layout, relaxed atmosphere, friendly staff, comfortable beds, fantastic breakfast, clean private beach, lovely massages, daily complimentary yoga classes. Would definitely recommend this wonderful resort! Prices are obviously high but that's what you expect in such an environment
Everything from check in to check out was fantastic. Rooms are clean and spacious, staff are extremely helpful and accommodating with great advice about things to do around the island. Not so much nightlife as such, but ideal for a relaxing stay. A la carte restaurants were nice, but the buffet is more than adequate with great breakfast and dinner options. Lovely beach area and pools.
Rooms were fresh, modern and spacious. Hotel facilities were accessible and the spa massages were just what we needed. The staff throughout the hotel, from check-in, to the bar and poolside restaurant and breakfast restaurant brigade were excellent in customer service.
The rooms were big and Spacious, and the bathroom had a hot tub. The breakfast was very good with a wide variety of food, also the Spa was absolutely excellent, lovely staff, thank you ladies for making my stay very pleasant with the 2 lovely treatments. 😍
Beautiful and spacious apartments, lovely and caring host Socratis made our stay relaxing and comfortable. Breakfast was fresh every morning, we were enjoying the gentleness of owners and quality of comfort provided . Can only recommend it! Thank you dear Socratis 💙

Arrived late. Check-in was quick with complimentary drink . Since we missed dinner, a pleasant surprise awaited us - a bottle of excellent local wine, sandwiches and apples. The room is spacious with a beautiful view. Breakfasts and dinners are excellent. Choice of food to suit any taste. Sunbeds on the beach are free and always available. The staff is very friendly. A wonderful hotel for relaxation. We will definitely come again
The Spa facilities were excellent - just like the staff. I was happily working my way down the list of treatments available. My favorite was the Hot Stone Massage Tiny pikelets / pancakes for breakfast is a MUST - for any guest! The Steam room and Sauna was a true delight - loads of big fluffy green towels to wrap up in afterwards. Kirsty on reception works overtime and ensures all the guest needs at covered. So enjoyed my time. We will be returning in Sept.
