Check-in process was very easy. You could always contact the two hosts either via whatsapp or by passing by the Café. The location and view of the apartment is amazing: extremely central, and even though pretty close to Istiklal pretty calm. If you‘re sensitive with noice while sleeping I would not recommend, since it is in a party area and next to a mosque. The apartment was not at clean as I would have wished (but it didn’t feel unhygienic). All in all we really enjoyed our stay and found that for the small price it was a great deal!
