Pros:
This place has a great location! It is VERY central to Taksim Square, Istiklal Street etc. You can reach the places within few minutes of walking. That was definitely the biggest plus.
Communication with the host was very good. We had some issues, but he helped in resolving them quickly and was always available on WhatsApp.
Check in and check out was very easy and hassle-free.
Cons:
The building is old and so are some of the items in the accommodation, for instance the iron, the sleeping arrangements, the storage options. If these things were improved, it would have been a more comfortable stay.
During the time we spent in the accommodation, the Wi-Fi was very slow.
