Avoid! I've traveled to nearly 50 countries and have stayed in a wide variety of hotels and hands down, this was one of the worst. Hotel staff mixed up reservations and gave our room away. As a compensation, they offered to pack a "free" breakfast for us early the next morning, as we had an early flight to catch. The breakfast was already paid for and they offered this as a compensation for their mix up. Despite having a receipt that verified a paid breakfast, staff was adamant it was not. They wound up compensating by $14USD in cash after a lot of negotiating.
This was the last night on our anniversary trip and disappointing. Paid for a room w a sea view and wound up in a cramped room- bathroom door wouldn't stay open and even a quick shower flooded the bathroom floor because of poor design. Lumpy uneven bed and half used hygiene supplies were left from the guests beforehand; was the room cleaned prior to our visit? Mini fridge also did not work in the room. All in all, this was a mess of a hotel- would not recommend to anyone. The only perk is it's location and being so walkable to various sites around SultanAhmet. This was my 3rd time to Istanbul- will definitely be coming back to Turkey but never this hotel.
