Nice and fairly clean apartment in a great location. Only a couple of minutes from Taksim Square. Access to Taksim square is uphill but this wasn't an issue for us.
Very friendly and helpful host who speaks fluent English. They provided us with whatever we asked for, made good recommendations about local cafes and restaurants and also kindly agreed to store our luggage for a few days as we had weight limits with our domestic flight. They are also very quick and responsive when it comes to communication.
The apartment itself has all the basics you need for a couple of days. The hot water and heating system were working pretty well and we stayed warm in late December. However, the apartment flooring near the kitchen area needs some repair as small part of it was sticking out and we had to put a basket on it cover it up. Hopefully this will be fixed by the host to prevent injuries. Bathroom, bed sheets, linens and pillow cases were acceptablely clean.
Thanks Umut! We enjoyed our stay!
