I and my husband made this apartment our base while visiting Istanbul.
It is a cozy quaint apartment on the 4th floor. Much like the pictures tell you. Very clean and has all basic modern amenities.
The building has good security but no lift. However, volkan insisted to volunteer and helped take my heavy luggage upstairs. The host is friendly, helpful and responsive.
The apartment is a 5-10 min walk to istiklal street and taksim square which is pretty much where the party is! We stayed for 3 days and had a comfortable time.
P.S. This was the first time we stayed in an Airbnb in a foreign country ditching hotels and hostels and was a pretty good and comfortable experience.
