Myself and three friends stayed in Yesim and Sashah's flat for three nights. The facilities were great, especially the lounge area and adjacent bedroom. The flat was in an ideal location, very close to Taksim Square and to key metro and tram stations. Sashah was very friendly and helpful - she went out of her way to come round to the flat to give us tips on how to get around, where to go, etc. Definitely recommended.
