Excellent.
Every morning we had a freshly made coffee and pastry of our choice at Andreotti pastries (downstairs)- which is an excellent bakery/cafe. Tasty!
The room was clean with a television and an en-suite.
Location was great- close to a bus stop and a train station. The main road was filled with good quality restaurants that cater for the locals mainly so the food is very authentic- more so than most of the city centre ones (and cheap). There is an ice cream place 4 shops along from this place which does the best ice cream ever!
Marco always picked up the phone and offered advice/help as needed.
On our first night he sat us down and went through all the important places in Rome and how to get there etc. It was very helpful.
Room had air con- which was fantastic during the hot days.
To sum up:
This place has the quality of a hotel, in a very affordable area with good commuter links and gives you a feeling that you’re not a tourist with an excellent super host.
