Overview: The place was more than okay, location is great, very close to the Grand Bazaar, a lot of supermarkets nearby, small shops and even a park for kids. Tevfik was a great host who waited for us, check-in was simple and okay.
Slight negatives : Cleaning was okay, not perfect and there were some issues with the boiler (not getting constant water for 5 people was a problem sometimes). We also had to wait a couple of hrs for our room to be ready, which wasn't a problem for us, but it could be for others.
PROs : Apartment is big, rooms are more than enough, very close to the Bazaar and Hagia Sofia, Topkapi Palace. Neighborhood is full of supermarkets, small shops, restaurants a couple of minutes away (Please explore the surroundings, a lot of hidden gems)
Overall, we enjoyed our stay and Tevfik did his best to help us out where there were issues. Went there as two couples and a baby and all was well.
See you next time, Tevfik.
