A lovely apartment with a comfy bed not far from the Altare della Patria. We like walking and were able to access everything we wanted to see in Rome without ever taking public transport or taxis. The room was cleaned regularly and had a range of good amenities.
Our only grumble was that the check in/out was not as smooth as it could be. We were only given one key when we arrived because the previous guests had the second one. We only discovered this when I went to ask for a second key as a key is needed to turn on the electricity for the room. I wanted to charge my phone while we went for a quick wander. The lady at reception then told us we could have the second key when the other guests gave it back, and that we weren't allowed to leave the electricity on anyway.
We were therefore a little worried about our belongings. A safe is provided in the room, which we left our valuables in, but obviously we couldn't use this for everything!
I think the thing about the electricity was a misunderstanding, as when we returned the key had been put into the slot for us.
We were a bit confused as to why the other people had a key, but we discovered why when we came to check out: the reception is not staffed full time. We left our bags there for the day, but with no guarantee that someone would be there when we returned, we also took a key.
It wasn't the end of the world and we still liked the apartment, but this is why we would give the listing 4, rather than 5 stars.
