Our family of 7 checked in after 22h30 and we opted to do a self check-in to save on the fees but we found that we were outside in front of the building with no way of getting in. The neighborhood didn't look very safe on first sight (it got better during our 7 days stay) so it was not a great feeling. Unfortunately, it was very hard to communicate with Claudio that we can't get into the building because none of the units in the apartment he told me to ring was responding. So our family was outside for at least 20 minutes with people in the streets gawking at us. Someone what uncomfortable as we were extremely jet lagged.
Long story short, if you are an English speaker please make sure to get clear instructions from Claudio and you are able to talk to him.
The apartment itself is ok. Not luxury and I would say it is like a 3 star hotel. It is fine and has a lots of space for our family. We are grateful for the space and close proximity to the main train station. The neighborhood does have some charm during the day. Sometime at night it is seems not the best neighborhood but we walked home after 23h00 with our young kids and it was fine. I wouldn't let my kids walk alone at night around this neighborhood.
If you stay at Claudio's place, you must try Al Caffè Romano which is to the right and 1 block down outside of the building on the other side of the street. They open early which is great if you are jet lagged! Great cafe with regular local customers and you get a taste of the Roma life.
Thanks Claudio for your apartment!
