Convenient flat, really close to the train station (just two stops from all the main sites). Well stocked kitchen and large enough rooms for four people to stay comfortably. Everything was clean.
Check in and Checkout was really convenient, he even allowed us to go in way before check in time to drop off our bags.
Not especially walkable, the Vatican and main Roman sites all require public transport or a long walk. But it’s a private, nice neighbourhood, and next to the only Egyptian pyramid outside of by Egypt, so that was cool.
