It's in a very convenient location- one street away from re do Roma Subway, but is also potentially walking distance from a lot of sights. Massimo's flat is on the 7th floor, but there is a service elevator you can use. There is a key for the apartment block, flat and room, so security is good. There is air con in each room (found a half hour eco blast before bed generally what was needed), and you can leave windows open 24/7. Place is clean and well decorated, there is a kitchen with oven and hob, but chose to eat at local restaurants (Massimo's suggestions are excellent, much better authentic food at way better prices than usual Rome prices) and very close to his place. Massimo has excellent English and will communicate swiftly through air BnB app, WhatsApp or phone calls if he is not in. Fair warning- as it's a flat the walls are a bit thin, but I feel there are way more pros than this common unavoidable issue.
