Emanuela‘ place was perfect for my needs: it is close to Termini train station (10min walking) as well as to the main tourist attractions and important places in Rome: Colosseum, Fontana di Trevi, Piazza Di Spagna, Via Del Corso (as they were so close, I used the metro only at arrival and departure).
In terms of security, the apartment is very safe (i.e. there is one locked door at the entrance of the building, another one at second floor where the apartment is located and the last one at the apartment itself). Also, it is situated on a circulated street, where I did not see suspicious persons, etc.
The apartment has an unique modern Scandinavian design and it is silent (has a smart tv, air conditioning etc). It does not have a separate kitchen, however I didn’t need one as I wanted to eat in town (to try all the Italian food). Moreover, each morning I found in a basket in front of the door the breakfast prepared by Emanuela.
Emanuela and her husband Andrea are very kind and civilized persons. They helped me with instructions at arrival, provided me with the map of the city and explained where all the interesting places are located. They speak well English and were very responsive. In short, it is a perfect location for a pleasant vacation in Rome.
