The flat is really nice, right outside the Metro station.
However the neighbourhood isn't great and can be a bit daunting especially if you are a young female or elderly person returning after dark to the flat.
Having said that our host was very reassuring when we expressed our concerns and told us the locals weren't anything to worry about and were just hanging around and "chilling" in the evenings.
The accommodation suited us because we were out for most of our stay visiting the attractions.
If you're looking for a place with a sofa and TV this isn't for you.
Thanks Denis and Grace for your hospitality and good communicating. Very good hosts.
