Location - really good, I was quite pleasantly surprised, Balat is a chic (I dare say trendy/hipster) neighborhood with many beautifully decorated cafes. I also felt it was quite safe. At first you may notice that many buildings are quite old / derelict (since many are 50-200 years old) and that may throw you off slightly, but if you give it a chance you certainly can see its charm.
Host - Isil is really an excellent host; she was on-time for check-in, she offered to show us the area, she always responded quickly via WhatsApp and helped with everything we needed. She also speaks excellent English and you'll have no issues communicating with her. 10/10
The flat - The flat is newly renovated, clean and looks very well (as you can see in the pictures). We had everything we needed and were able to cook, wash clothes and relax. There are a few negatives: The kitchen is a little on the small side and the flat has a few quirks (noisy floor, annoying thin front door) but in all fairness these are all just minor annoyances. Overall it's cosy and we certainly had a pleasant stay.
Would definitely recommend
