Our host was very useful and friendly. The location is very good for tourist as it's quite close to very central and popular area Taxim square and Osmanbay subway station. Despite of the closeness (5 minutes work) to populated street with a lot of shops, cafes and restrains, the apartment is quiet and good for stay.
Also there is a lot of space inside enough for comfortable living the company of 5 adult people. Also the thing that you need to be prepared that in all the area around Taxim they have the water outages for several hours time to time.
