The airbnb is located perfectly as it is really close to the city centre so you can have a break during the day of visiting the downtown at your room, moreover it is even closer to Termini which makes it super easy to catch a train or bus and discover more remote places. Furthermore the neighbourhood is extra safe thanks to the many embassys and government buildings. There is an ice cream shop just in front of the flat which is open till 24:00 and sells one of the best ice creams even compared to the famous italian brands. There is a pizza shop just around the corner where you can't sit but your room is like 2 minutes away and the pizza is outstanding, the best we've ever tried in Rome and we had tried some and it is quite cheap as well.
The only downside is that the walls are not that thick and if you have careless tourists in the other rooms of the airbnb it can be disturbing but it can happen anywhere if you don't reserve a whole apartment. Other than that the whole place is super clean, the beds are really comfortable and the air conditioner is very effective. The breakfast is mostly sweets (good ones) and you can have coffe, energy drink, fruit juice and milk throughout the whole day which is quite nice. We booked a room without private bathroom but there was a vacant room with one so they gave it to us for free furthermore we could leave our luggage in the apartment after checkout which was super useful as we had a flight late afternoon.
All in all, this airbnb is awesome and totally worth the money, would recommend it to anyone!
