Maria and Walter are wonderful hosts. Due to a train delay, we reached the house very late in the night and Walter waited for us without complaining , to had over the keys and show us the space. He was even kind enough to help us with the bags and everything. There was breakfast for the next morning, coffee, tea etc which was very convenient. The communication with Maria was excellent and she is very friendly and kind.
The house itself was sparkling clean and is in a perfect location, you can literally walk to all attractions in Rome, starting with the Colosseum. We did it with a baby, so there is no reason to believe why you can't. There is a train station and also a tram station very close which you can take to goto vatican or other place. Overall, we had a great stay and would recommend to everyone without hesitation :)
