Great value and great place to rest after a long day walk around Rome.
The self check-in information is so useful, the place is clean (the room is being cleaned daily), the air-conditioner is very helpful especially after a long day outside, and the location is close enough for a 10 minutes walk to the Colosseum. The nearest metro station is just a few minutes walking and the area is quiet and nice. The host is very responsive to any inquiry, and you can use the small kitchen to prepare easy meal (no oven or stove, but they provide microwave and water heater). It will be perfect if in the future they can provide a washing machine and dryer; which will be very helpful for a long term traveller (can not find any laundrette near the building), but they did not listed it anyway so we already know this beforehand.
For the price, it is a great value of money.
