Appartments are good, the most pleasant thing we enjoyed is an extremely comfortable bed, which is the most important after long walk ;)
Everything was clean and we had all we needed for our short stay.
The location is perfect for the tourism purpose - Colosseum is about 5 minutes walk, 2 metro stations are somewhere around 10 minutes walk. As well as 2 supermarkets in the same distance and quite a great wine bar.
In addition, I would like to mention Andrea`s extreme patience and kindness, when he came somewhere around 10pm to show us that we mixed the entrance door and he was not able to open them for us remotely (sorry for that, again).
Other things to notice - nice hot shower, pretty quiet building and surroundings, welcoming breakfast stuff (jam, croissants, tea, and coffee), warm room, taking into account January.
