The staff was not helpful at all. Any requests we made were either ignored or met with a flat refusal — including a simple request for new pillows, since the ones in the room were extremely old, flat, and uncomfortable.
The room was not cleaned daily, which was disappointing. The towels and sheets were worn out, with visible tears and stains, and the overall cleanliness and upkeep of the place left much to be desired.
On top of that, the hotel is located in an extremely noisy area. If you're a light sleeper, this will definitely be an issue. The only upside is that it's close to Taksim Street, but that’s about the only positive I can mention.
