This home is really lovely and comfortable, it is probably the nicest AirBnB we’ve experienced in this regard. The hosts are accommodating and helpful. The wi-fi is reliable and fast and everything else is in good order and functional. The neighborhood is culturally diverse with a local feel. It is very charming and easy to access places to eat and shop. There are multiple public transport options to get to other parts of Istanbul, including taxis. We stayed a month and loved every minute of our time here.
I would say you want to be reasonably fit, it is a steep walk uphill and/or downhill from public transport or local cafes and shops to the home, the four flights of stairs in the home are also steep and the water is non-potable so you have to carry big jugs from the store a couple of blocks away up to the house for drinking, cooking etc.. As reference, my 75 year old mother did just fine staying with us on the second floor bedroom of the home for a couple of weeks. Also, it is a dense urban environment and the neighborhood is going through a huge renewal so plan for construction and street noise during the day, we did find it to be quiet late at night so sleeping wasn’t a problem. With that in mind, I highly recommend staying here if you are able.
