I spent 3 nights in Gonul's house. The room was quite small but that was no problem for this short period of time. I shared the bathroom with my host which was not any problem either.
Gonul is a very friendly person, a perfect host and she let me fell very welcomed, I enjoyed her breakfast and talking to her. Everything was as advertised and very clean. Her house is located in a quiet road off Brixton Hill and the underground station Brixton in only a 10 min walk away, busses are just 3 min away.
Do not miss to visit Brixton market (located at the Brixton station) and the nice little restaurants there.
I only can recommend this room.
