Great location - close to the Vittorio Emmanuel train stop, and a 20-30 minute walk from Roma Termini (we took a train from the airport to Termini and walked it to the B&B). Also close to the Colosseum which we were able to see twice day as we made our way back to the B&B - such a treat!
Check-in was fairly smooth - we didn't meet Anna but we were able to pick up the keys using the instructions she had provided. The building has an elevator which is a plus if you have trouble with stairs. The room was a compact sized space with a really clean and modern bathroom. Bottled water for 1 Euro was convenient. Breakfast is pretty substantial (boiled eggs, toast, cheese, cereal) and provided in the little kitchen. Thanks Svetlana for making us coffee both mornings!
My only comment will be to ask if the room has an AC remote, in case you are checking in late and don't get to meet Anna or the staff (as was the case for us). I emailed Anna asking for the AC remote once we got in the room and she said the staff will give it to us the next day at breakfast - wasn't sure why we had to wait overnight for it..? We cracked a window and fell asleep since we were fairly tired and it wasn't really a crazy hot summer night. But it was fairly warm and we would've liked to have the AC running. Minor pain point, but good stay overall.
