We stayed for 36 nights in this place and this is what we have to say:
1. We were amazed how beautiful is the neighborhood, there are cafes, supermarkets and everything you can think of, one of the best in Istanbul.
2. Public transportation is the best!... you can take busses, metro, train an boat. Easily to go everywhere in Istanbul.
3. Mustafa is an amazing host, he is always trying to help and most of the time he is at work.
4. The bedroom is pretty good, have a lot of space and the mattress is comfortable. The apartment have everything you need to cook or just relaxed.
If I go back to Istambul I definitely will take this place, so if you are thinking about it this is your best change in terms of price/quality. Don't forget to see the sunsets, are gorgeous!!!
