I booked this flat for 4 adult people for one week. It was a really comfortable journey. As soon as I booked online, the follow up made by the agency was perfect, they answered my emails very quickly.
The apartment is at 10mn walking from the main street Istiklal.
It was very clean with everything you need. And the agency which takes care of the flat is just downstairs in case you need something. I recommend 100% this flat !
