Great location close to lots of public transit and within walking distance to the Colosseum, parks, restaurants and groceries. The arranged airport transit fell through, but we were able to get an Uber quickly.
Andreino welcomed us very pleasantly and helped us get situated. We had to take a couple trips in the lift to get all our baggage up, but it worked out fine.
Just fyi, if you come in the summer, be aware you'll probably want to sleep with the bedroom doors open to help with air circulation, as the air conditioning is in the front room. The ceiling fans in the bedrooms help.
The shutters are great for blocking light and noise. There is just one window above the dining table that I don't think had a shutter, so it let in light quite early. Also, the bedroom with the two single beds has those windows to the front room, so light comes into the room if someone is up at night and using the kitchen, etc. This may be something to take into account if you come with young children and they go to bed earlier than you or are prone to waking up very early with the sun in the summer.
We found that the hot water in the shower was a bit inconsistent. Just don't wash dishes while someone is showering, and you'll probably be good. The towels, pillows, sheets, etc. were great. The kitchen is well-equipt.
Communication with the host was quick and easy. All in all, this is a good, safe place to stay.
