We stayed in Vefa's place using 3 beds for 6 nights. Needless to say, we had a well rounded experience. The place is safely located and the housemates were friendly. The usual amenities are also well stocked -- Vefa takes care of that. The shower can be a little bit of a pain (it needs to be pressed every minute or so to maintain flow) but one gets habitual of it. Also, Vefa's hospitality is commendable and worth mentioning.
Overall, if you're looking for a clean minimalist and safe place to stay.; at 20 bucks a day its great value for money .
