This 5 star review is primarily for the tremendous location and the kindness of the staff upon checking in and out. The location is pretty much as good as it gets. It is one minute from Galata Tower and a short walk to Galata bridge that leads to the old city and all of the historic sites. Additionally, the folks working at the hotel are very kind.
The room wasn't impeccably clean, but there was nothing egregious. It is a really good option if you are coming to Istanbul.
I recommend it!
