Clean apartment with friendly housemates. I really enjoyed staying at Tatiana's place and the best thing for me was that her kitchen was fully equipped. It was important for me to be able to cook for myself and her kitchen had everything and more-- so it didn't feel like I had to buy anything additional. Lots of fridge and cupboard space too.
The only small issue I had was that my heater was broken so I had to be without heating for a few days in winter (not anybody's fault) but she was very responsive over text and tried her best to get it fixed though there was a bit of waiting.
Also I did love my balcony :)
