I stayed for 7 nights at the Airbnb and had an overall ok stay. The place is very conveniently located and the host is quite responsive.
If you are planning to party in Istanbul and only sleep at 3 or 4am, this place might be perfect to you. There is a very popular club just downstairs and you can even feel the vibration of the music not even mentioning hearing it. The party started on Wed onwards when I stayed.
Meanwhile it’s located in this ally way and probably because of the club crowd, there is constant smell of piss downstairs when you leave or come back.
Inside of the apartment is fine but the sofa is stained. Personally I will choose a different apartment in a quieter location which there are plenty of options around.
