Nice apartment and the views of the Bosphorus don't disappoint. The living room is spacious with two couched - one for looking at the river, one for watching TV. The decor, carpet, etc are a bit older in style, but the apartment is still pleasant and comfortable for several people to stay at. There's a little balcony for having coffee or a drink overlooking the river, but this part of istanbul can tend to have very noisy traffic.
The location is great, right at the edge of Cihangir, one of the hippest and most up and coming neighborhoods in Beyoğlu. It's about 5 minutes from dozens of bars and restaurants, great food, and, of course, endless street cats (kedi). I'd recommend this apartment for anybody who's excited to visit Cihangir and explore the greater Beyoğlu area (which has 4m people so hardly a small neighborhood) -- we didn't have to go to far beyond but I also think it's a relatively good location to base yourself at for greater Istanbul.
