This is a fantastic place to stay. Whether for work or holidays. Everything you need is within a couple of blocks distance. Supermarkets, cafes, bars restaurants, deli shops... It is a real Roman neighbourhood but within walking distance of top tourist attractions, including the Colosseum, the Palatino and Terme di Caracalla. It is very well connected to public transport, including the metro, tram and buses to everywhere in Rome.
The apartment is very comfortable and extremely clean. Double glazed windows, heating and air conditioner mean you can be comfortable any time of year. The water pressure is very good (something not easy to find in Roman apartments) . The covered terrace facing a courtyard is very nice and it has good wifi reception so you can relax outside and access the Internet at the same time. Even when it's raining. Modern kitchen, dishwasher and washing machine round everything up.
Marco and Georgeta are very helpful and friendly. They respond quickly to any questions or requests and they have good advice about things to do and places to go.
I stayed there for 6 weeks while working at FAO, which is within 20 minutes walking. I will happily stay there again for either holidays or work. Overall a great experience.
