Great location! Everything is right here, no need to go anywhere - pubs, shops and restaurants are one step away from this apartment. This is also a minus - nightlife in Istanbul is very noisy and you will be right in the middle of it, so you might feel some discomfort. One room's windows look directly on the street and, since this is the first floor, you will hear all the conversations and fun from nearby. For us this was not a problem since we were noisy by ourselves, if you know what I mean : ))))) First floor actually is 1.5 floor - under apartments there is a bar or some shop on the sub-ground floor - so don't worry, there is enough height, nobody will put a face into your window. We were pretty surpized about safety - we left windows open and walk away to check out the city, nobody got into apartments.
Berkan and his wife are super friendly, very open and always willing to help, suggest and advice, always online. I definitely recommend anyone to deal with these people!
P.S. Ceiling is great!
