Great place to stay in Istanbul. The room was fairly small but had all that is needed for a comfortable stay. The rooms on the lower floors can be a bit noisy because other people have to pass by, but when we stayed all other guests were very considerate of not making any noise.
The location is next to perfect, in a fairly quiet street just in the otherwise lively neighbourhood of Galata. Many great restaurants and shops nearby, from Galata it's easy to travel to the different parts of Istanbul.
We ended up extending our stay because we liked it so much. I recommend staying here if you're planning on visiting Istanbul.
