This was our third time in Rome (previously in 1980 and 1984) and enjoyed every single minute of it. The Domus Romana is a nice and very charming small hotel very well located even for us that are more than 60 years old. There are several small places to eat, have a beer or a glass of wine in the same street. Just around the corner there is the Via Nazionale, where you can find anything you want; shops, restaurants, a 24 hrs drug store and a small super market (all these within 1 minute walk).
If you walk 5 minutes you are in the Piazza della Repubblica, where you can take the Metro, and you can go from there to any where because one stop from that station there is the Plaza Termini where you can take all the buses and trains to any where within the city or elsewhere. There you can buy a one day pass, that you can use to take unlimited any bus or Metro for one day (4 Euros) or the three days for 11 Euros. Along the Via Nazionale you can take a bus to St. Peter´s Square or any where in the city (bus stop 2 minutes from the hotel).
The room that they assigned was clean, spacious, with a nice kitchenette, very beautifully decorated ceilings (wood work) but a little bit dark in spite of several lamps. There were some details in the bathroom like shower caps, shampoo and a nice pair of slippers.
The breakfast room was cozy, specially in February when Rome was very cold. The breakfast included coffee,juice, bread, croissants, meat, cheese, cereals, yogurt, pastries, cake, hot chocolate, in a nice, clean atmosphere. The two persons that are taking care of everything are very efficient and discrete. You can ask for expresso coffee and immediately you have it. In summary you can start your day very well fed and spend most of the day until lunch. There was a toaster for the bread and I mention it because some one who wrote a review says that there wasn´t.
They have internet in the lobby at a reasonable price and once I asked for a nice restaurant for my wife and myself and the reccomendation was good, although some how expensive. The cafeteria around the corner in Via Nazionale serves excellent spaghettis with shrimps (8 Euros) and a very nice meat with vegetables (14 Euros). There also you can have pizza, have a beer or wine. Drinks in Rome are 5 Euros every where (beer, soft drinks, wine).
In summary the hotel is very well located, transportation is readily available very close to the hotel and you can walk any where from the hotel. 15 minutes to the Fontana di Trevi and from there you can start your walked tour to all interesting places in Rome. You can go to Plaza della Repubblica and take the Metro for Piazza di Spagna. Walk 20 minutes to the Colosseum, 10 minutes to Monumento a Vittorio Emanuele and so you are right in the middle of everything.
I would reommend it to any one in my family and surely when we return to Rome, will stay in the Domus Romana.
