Stayed here with family, 4 of us was comfortable. Three rooms but they made two rooms for us as one room had double and single and another was double. We ended up using the third room as we had a teenage boy with us who didn't want to share. The third room was not made but my brother just used the blankets which already had covers on them to sleep on the bed with. The apartment was beautiful very clean and well put together. The kitchen pots and pans could have a couple more for bigger families but all other dishes were very well provided. Apartment is little far from centre but there are buses and metros near by so there is no issue for getting to tourist attractions. Loved our stay no issues
We stayed here last month for two nights and thought it was a really nice apartment. It isn't always easy to find an apartment that can comfortably accommodate 8 people (3 bedrooms, 3 double beds and 2 single).
The whole apartment is renovated with a nice bathroom and kitchen.
Fairly close (5-7 min walk) to Ponte Lungo station which connects directly to Roma Termini and Vatican city.
Having said all of this, if you are visiting for a short time I would say it is a bit far from the main tourist attractions. We walked to Colosseum which took around 40 min. Therefore, I feel that if you are staying here for a longer visit (4 nights +) the big apartment in a quiet location away from the chaos of the city, is nice to have. However, if you are staying for a short time, you might want to find a place a bit closer to the main attractions.
Additionally, it wasn't the easiest to find, make sure you are in touch with Alexia who was extremely nice and helpful!
