The host: Eyp was an excellent host. ansewr to all questions and respond to all your needs and concerns within minutes.
The location: This apartment is close to everything. Within 2-5 min walk you can get to best Turkish bath in Istanbul, A highly rated and popular breakfast place, metro station, Istiklal st and all the shops and resturants in there, convenient stores, a great bakery which makes turkish bread and pideh, and an awsome local bar. Also you can walk to Bosphorus which is 15 min walk and Gala tower which should be 10 min walk. The only thing about the location that you should pay attention is that this apartment is located on a very very steep st. If you are travelling with small kids and stroller or elderies, I would not recommend this place. Also, the street is very narrow like many other streets in this neighborhood and the garbage disposal system is not the best, so it may disappoint you. This is the old part of the city so adjust your expectations.
The apartment: very very clean. Well equipped with all you need. For me the highlight were the smart TV with Netfix, Amazon prime, youtube,... AC, traditional tea maker, and a washer/dryer unit which really dries the towels :). This apartment is on the first floor with just a few steps. I was worried about the noise at night specially for the bedroom that opens to the st but the windows really sound proof and when you close them you don't hear anything. On the negative side, there is construction going on in the building and there is a wiered smell in the hallway. Also the hallway is not in the best condition as it is old and not well maintained.
All together, I highly recommend this place.
