Selina home is spacious, extremely clean Nd at a very very convenient location off Istiklal Street.
We stayed at Selim's home for 5 days and it was amazingly comfortable. Selim himself was always available to give us suggestions and recommendations on food, tourism, shopping and cafes.
We would highly recommend anybody visiting Istanbul for the first time to stay at Selim's home as the convenience of the location is above all else. It's close to multiple T1 stations as well as Taksim square (which is 6 mins away).
