We spent a week at this place. We were well greeted, on time and given information about the apartment and the neighborhood as well as a phone to call in case of need.
The apartment has been redesigned and the photos do not quite match the reality, however, this is a place that we quickly made 'ours'.
It's clean and cozy. We were only there to sleep and eat in the morning so we didn't need more. There is a supermarket 2 min walk from there and it's not far from Termini station (+ -15min via the university area in the San Lorenzo district, we found this itinerary to avoid going to the station area in the evening. As in every city in the world, the station quarter is not the friendliest at night but we didn't have any problem).
The apartment is located in a lively neibourhood so if you have a light sleep, take earplugs with you.
We visited Rome by foot almost all the time, from the center it takes about 1 hour to come back but there's a bus station at 300m. We wanted to appreciate the city by night.
A new Internet modem was installed during our stay and there was no more concern with the wifi. A microwave was also proposed to us but we didn't need it. There is a washing machine in case you need it.
It is true that the bathroom is very small but there are the basics. There are shampoo and shower gel available.
We really enjoyed our stay at Amen's place and will be back if we go back to Rome.
