I definitely recommend this Airbnb for everyone who wants to have a central location and wants to explore a lot! The apartment is located just 2 walking mins from the metro station "Osmanbey", which is ideal for getting around in Istanbul. But also the location of the Airbnb itself is great, as it is in the Sisli / Nisantasi area. Supermarkets, cafés, restaurants, pharmacies - everything is around the corner.
Concerning the apartment itself, we really think it was a fair price for the space we had (especially compared to other Airbnbs in the area, which we checked out). We stayed there for over a month and were well equipped as we had a stove, a washing machine, and a dishwasher (but no oven, which was not a problem for us though). The apartment is in the 4th floor and there is no elevator and stairwell is a bit rocky, which is important to note for the people who maybe are a bit older / not as fit. But for us it was no problem!
All in all I would definitely recommend this place, and the host Melike was also extremely helpful. We would definitely stay here again!
