Having read some previous negative reviews about the hotel on this site (after i'd already booked to stay there), I was expecting very basic accomodation, so it was a wonderful surprise to find that the negative reviews were inaccurate (in my humble opinion). The Domus Julia is clean, tidy and very comfortable. The room was functional and attractive enough & air conditioned. The bed was was comfy and our room was quiet. Plenty of piping hot water for showering etc.
We found the staff to be very friendly and good humoured-they are available at the front desk 24/7, should you need them and spoke good English. They are able to book day trips for you and provided a very helpful map of the city and leaflets about travel options.
Breakfast was good, offering a range of pastries, cereal, meats, cheeses and beverages.
The location was absolutely suberb! The Barberini Gallery is at the top of the street and Piazza Barberini is a two minute walk away (a metro station is located there which links to Vatican, Colosseum, Termini station, etc and is very easy & safe to use). It is a 10 minute walk to both the Trevi Fountain and The Spanish Steps, and there are plenty of bars and restaurants at hand (which is not the case in every area).
I highly recommend the Domus Julia. Our stay there was fantastic.
