Uygar is definitely a wonderful host! Staying in his apartment was a big pleasure for us.
His apartment is placed in a lovely district in close proximity to Istiklal (but avoiding its rush and crowds) perfectly representing a traditional spirit of Beyoglu. Thus it represents a great combination of "living-like-a-local" experience with ease of navigation (just be prepared that Istanbul is very hilly, so be ready to do some sports).
A room has enough space and all the required facilities are there.
The most remarkable experience is though a communication with the host: Uygar is very supportive and is always ready to share his valuable advice in regards to Istanbul's hidden gems, events happening in the city and his insider view.
Surely recommend to everyone!
