To get to the studio you have to go down two stairs, the first stairs are no problem, but with the second the bad smell starts. The studio itself also had a particular smell, so if you are allergic to it like myself I would think twice about renting the place. I had to cancel my reservation after 6 days because I got ill of it.
The location of the studio is good, Cihangir is a very nice neighborhood; a lot of cats and cafes.
Warm water is a problem, like others before me have already mentioned in their comments.
In my case the place was not cleaned, everything was sticky, no one had vaccumed the place and there was a naked snail in the studio. This might be because Astrid was out of the country, but sending a cleaning lady would have been appreciated.
