Everything was great, really. The flat is situated in a lovely neighbourhood, not so loud for Istanbul standards and not so touristic either. Lots of beautiful places around, including nice restaurants. The apartment itself is arranged in a minimal way, which was a great feature for us; but one thing, in particular, is great -- a yoga mat and a massage roller, which you'll love after the whole day of climbing up and going down back and forth the Istanbul's terrain. There is also a nice view from the big window that makes the whole daily room even more spacious and gives room to breathe after the whole day. The shower + toilet combo is a bit peculiar, but I guess one can get used to it. Maria was also very responsive and made it very easy for us with checking in & out, and kept in touch in case we needed anything (she even brought us the iron after we asked for it, which was also super nice). All in all, highly recommended!
