It's a good place to stay for a couple of nights in Istanbul. The apartment is tiny but has everything you may need during short term rental. One of the main benefits is its location: 5-7 minutes walk to Galata tower, Istiklal, and public transport stops.
Speaking about cons described in other reviews: WiFi speed was really poor, it's true (most of the time we used 4G instead); noise level is quite usual for Istanbul as for me; the apartment was cleaned well before my check in and I couldn't smell anything strange in the bathroom :), so no complaints from me at this part. Simply put, considering its price it's good value for money.
The host is very friendly and always tries to be of help.
