Unfortunately, we didn't get to meet Simone as she was out for the evening and a friend of hers let us in the apartment and provided us with all the needed info.
Communication was perfect though, and Simone promptly replied to all my messages.
The apartment is clean and brilliantly located in a quiet neighbourhood pretty close to all the amenities: suspension bridge and Clifton village are a stone's throw away and the city center can be reached within an easy 15-20 minutes walk, but probably it can take a little longer if you don't know the streets of Bristol, as it's a city that it's not that easy to orientate yourself with (or at least that was our 2-days visit impression).
There's also a regular ferry service along the Avon, which is a little expensive but it's worth it to see the city from a different perspective and all the barges turned into hipster bars and apartments. The boat also lands at Pumphouse which is just a few steps from the apartment.
The room is quite small but it suits if you're there just for a few days and you are not travelling with heavy luggage, which we were not :)
All in all, a nice stay in the charming young multicultural full-of-contrasts city of Bristol, which we loved!
