Born and raised in Roma, I'm a family guy with a Canadian wife and 2 daughters who loves to meet new people of different nationalities and backgrounds!
The overall impression is very positive, the apartment is well-located with respect to the city center (10 min walk from Re di Roma), and Giuseppe speaks perfect English (rare feat in Italy!). His advices on the best way to get to the BnB helped a lot.
I stayed in the 1-person "Olive room". It was small but tidy, all furniture in perfect condition. I put 4/5 stars solely because of problems with hot water in the toilet and the fact that the room door is not lockable, rendering it accessible by other guests.
The standard croissant-and-coffee breakfast is in a bar around the corner (closed on Sundays though), croissants are fresh and yummy :)
Booked very spontaneously, fast answering cooperative hosts who are offering simple but comfortable and recommendable rooms in the centre of Rome. A good place to stay.
I really enjoyed my stay at Guiseppe's. The room was cozy and clean, the breakfast at the cafe down the street was simple but satisfying, and the location was quiet and yet close enough to the heart of Rome. Guiseppe was extremely accommodating and quick to answer any questions or concerns I might had.
When we arrived at the apartment we were greeted by Guiseppe. From the moment we showed up he was super helpful and spoke great English. If it wasn't for him we would have been lost in Rome. The breakfast in the morning he supplied was great. He told us what busses and trains to take which helped us a lot. He also had free wifi and a full kitchen. I would highly recommend staying here.
