Unfortunately despite being a great location and Stas being really nice (and having two great pets) I think this spot probably isn't suitable for a lot of guests.
The main thing for me is the smell. Stas smokes inside the house, and whilst I'm sure she would have not smoked for the duration if I'd asked her to, the smell has permeated throughout the flat and it is very overwhelming.
Secondly, the cleanliness of the flat isn't great. My room was fine, but the bathroom/shower was consistently blocked, leaving you showering in a few inches of water at the bottom of the tub, often with a lot of dirt which was already in the bathtub. The shower curtain was dirty.
Also despite Stas' pets being lovely, her dog went to the toilet every day in the hallway to the flat (Stas said this would happen when I arrived). I was visiting from the UK, and had I not had an incredibly busy schedule all week I probably would have found somewhere else.
I've never left a bad review before and so I feel pretty bad about it, but feel I should give a fair representation for the future.
