Efe and his companions rent out 3 flats in Istanbul. My stay was at Artist's Studio, in between Osmanbey metro station and Taksim. Efe kindly picked me up and brought me to the Havatas airport shuttle at Taksim by car. I really enjoyed my 5 night stay in the appt, it was close to a conference I was participating in. The appt was clean, the bed was really comfortable, plenty of cupboards to put my clothes, wi-fi was working. The spacious appartment has some long tables, which I used to do some work. The kitchen is for basic use only, but I enjoyed eating out most nights at one of the cheap places around. Ok for breakfast though. The shower in the bathroom works, and in contrast to what some of the other reviewers wrote, I feel it is not bad. If you are used to inner-city European size bathrooms, this one works quite well. The flat is located on the 7th floor but there is an elevator. All in all, I would recommend staying here. Efe is super friendly.
