1 time there was no electricity in the hotel, but the aggregator strarted to work, and we had light. One time there was no water in the hotel, but they solved the problem in a 30 minutes.
Perfect location, everything was in a 5 minutes walk, we didn't use public transport. We booked a normal room, but there was some problem about booking, so we got the "Ayasultan" deluxe apartment on the top floor. This apartment was full of luxus, sultan style furnished, and had a perfect view to Topkapi Saray, so we liked it. :) The rooftop restaurant is very friendly, and has a wonderful view to the city, too. The breakfast is abundant, it had wide sortiment of salty and sweet pastries, ham, salami, and 5 type of cheeses, yoghurts, vegetables, eggs, and a lot of muesli, so we could begin the day with full stomach.
