Upon arrival we were unpleasantly surprised to learn that they were "overbooked" and had to downgrade our room to a room with NO windows for the first day (although they tried to make up for this by a free dinner, which was quite fair). More unpleasantly on the next day they were trying to convince us to accept a twin room vs the booked double, and it took some arguing with the hotel owner to finally get the initially booked room.
As to the hotel in general - the rooms are somewhat outdated, especially the bathrooms (shower head did not mount well, some other details in need of replacement). The WiFi not available in rooms, and often very poor even in the lobby/pool area. The cocktail bar, which was praised in some comments, was very poor, with cocktails barely containing any alcohol.
The rooms were of descent size, well-cleaned (although the cleaning agent used left a strong chlorine-like smell). The pool area was rather convenient, with a child pool and sufficient number of sun-beds even at peak hours. Receptionists and other staff were rather friendly and willing to help. Breakfast was reasonably diverse for the low price (just 5 Euros per person), with a basic supply of vegetables and fruits, bakery, eggs, yogurts etc., all being replenished regularly. I would recommend the restaurant "Something Special" - just opposite the hotel - a very pleasant family run restaurant with great food and very warm staff, which also has a small playground for kids. About 200 meters from the hotel (in the direction away from the center) you will find a descent child cafe (The Fun place), open from 18:00. Mostly the best restaurant are to be found closer to the town center.
The location is generally good, with a 500 meter walk to the beach and a 10-15 minute stroll to the center of Faliraki. Several decent restaurants are within a short walk, with the hotel restaurant serving descent food as well.
The beach was sandy, with shallow water for about 100 meters from shore (good for kids), and never crowded (unlike the parts closer to the center of town). Sunbeds are 4 euros per day.
