So a lot to say about the stay
Overall - it was wonderful. All the needed facilities were available and definitely eased our stay in Istanbul. You never know when you need a washing machine. Warm water was always running and the owners who greeted us did a lot to help us drag our luggage upstairs on the fifth floor.
Now the only minus is literally that - this is the fifth floor. You get used to walking up after a second time but if you have a lot of luggage like we did - be aware you will have to not only bring all of that up (even despite getting help) but also down.
Overall I’d say this is a good stay. The location and friendliness of the hosts was very comforting in what was a crazy trip and I’m glad we got to stay here. Highly recommend
