Nasibe's place has some nice things going on: The living room is very spacious, and the TV is equipped with a nice sound system and a HDMI cable. It was also impeccably clean upon arrival. It has everything you would need for a long or short stay. The location is amazing: close to a big Migros, a nice bakery and a lot of pharmacies. There is a gym on the same corner and its just 10 minutes away walking from the Osmanbey metro. The kitchen is small but with enough space for one person to cook comfortably. There is space to put your things. This may seem minor but for example, some hosts don't have space on their closet for your stuff. Also the internet speed is really good, up to 15mb and quite consistent even during snow storms, which is good for remote workers.
I had the bad luck of renting this unit for a month during the last days of winter. The unit has a central heating system, and the building manager turned it off/on at 11:30 PM and 6AM during winter. The living room is never warm as is too big for the 2 heaters it has. I had to wear the same clothes outside while inside most of the time. The bedroom gets warm by keeping the doors closed but by 3-6AM its already cold. It's not like you are gonna freeze but the air gets too cold during those hours. I had the bad luck of catching a cold and breathing cold air during early morning didn't help.
Other minor inconveniences: fifth floor & no lift. The dedicated workspace is a wooden chair which is not really comfortable to work from for long hours.
Other than that, is a good place. Nasibe is a great host, kind, cheerful, and very communicative with fast reply time. I would stay again during spring/summer/autumn without hesitation!
