We stayed for a week at Ramon's place and felt very comfortable. It felt very safe as it is tucked in behind his art studio and separated by a door with a padlock from the studio. To access the studio you enter the main door from the street and then the door to the studio with keys, then the airbnb is at the back of his studio separated by a door. He is sometimes there in the studio which is we liked as it was nice to see him and have a chat every now and then. We saw him maybe three of four times during our stay and he was very responsive by message if we had any questions.
We slept well , it is quiet during the night. The bedroom backs on to the stairwell of the building so we could hear people leaving in the morning at around 8.30 and then at end of day but our sleep was not disturbed.
Location is cool and close to tube stations. Lots of local bars and restaurants.
