Artist's loft was my first experience ever with airbnb. Overall the experience was satisfying with no surprises. Valentina was very kind and welcomed us in a warm way. She was even willing to shop some key-stuff for us (milk, bread, eggs), as we arrived late in the night. The appartment was as shown on the pictures and quite clean. The sheets and towels were fresh and the quantity exceeded our actual needs. The place was very quiet, we heard nothing during our staying there (4 days), we thought we were alone in the building. It was also very warm, we didn't even used the duvets during the night. Hot water 24/7. The absolute must after a day of wandering in Rome. And last but not least: metro entrance only 4 steps of the building's front door. I read it in the reviews but I thought it was an exaggeration and I would at least have to cross the road. NOT! Right in front of the building's main door.
The neighborhood was as expected based on other reviews. Lots of immigrants in the area, but we didn't feel that there was something to be afraid of. Yet, we never returned or left the building in the evening. We were every day getting home in the daylight.
I would recommend this place and if you ever stay there, don't forget to visit the gelateria recommended in the guests' book!
