Ernesto is a very friendly person, available and always ready to help.
The flat and atmosphere was great, well decorated and welcoming even though we spend most of our time outside. The only thing I would comment on is the cleanliness of the common bathrooms, which could definitely be improved.
The area is for sure the best in Rome to stay, quiet and very close to the historical city centre. Ernesto even shared a map he created with all the useful places (pharmacy, restaurants, bars, etc.) around the neighbourhood, great tool if you wish to explore the area with local tips.
Overall a very positive experience for a three-day stay.
