I am really glad we chose this apartment to stay in, and have only good things to say about it and our host.
The location is excellent - Istical and Taksim are just 5 min away on foot. Although it`s in the most vibrant part of the city famous for the night life, the street is really quiet and safe. The most convenient way to get to major sights is by tram, the station is just 10 min walk down the hill on the quay.(I recomend to bye Istanbulcart) The street just around the corner, from Firuz aga mosque to Taksim, has everything you might need (supermarket, bakery, kebabs, exchange, caffe`s that are always full with people)
The apartment is just like in the picture, and really clean. We were pleasantly surprised how well it was equipped - we had clean towels, shampoo, paper, all the utensils in the kitchen, even spices, oil, sugar, drinking water - everything you could think of.
We also had no problem on our arrival - the host`s friend was on time to meat us and take us to the apartment and Tolga was always available for any questions.
I highly recommend this place.
