My review is based on 7 nights stay between 14-21th August 2015. I wouldn't recommend to stay there for long period for 2 people, but a couple of nights should be fine.

We (my GF and me) were well received when we arrived and the room looks fine. But there was no free bottle of mineral water or wine as welcome gift, which I receive all the time in my previous stay in other places. The location is very closed to the Termini, about 7 minutes walk. I would say it is quite convenient to get anywhere from there, but still, better to live in the center of the city so you can easily get back after later dinner or late nigh walk in the city. And the Termini area is not very comfortable to walk in the late night, but that is typical for train station area.

The WIFI works fine, no problem to browse or watch video on Youtube. The stereo is not working though, so don't count on it unless they have fixed it.

The apartment never gets any sunlight, so it is quite dark. The room is very hot in the summer and the A/C is not powerful enough to reach on the loft, (it is like sleeping in a sauna room up there). We slept on the sofa bed downstairs instead. The stairs are very small and narrow, it is difficult for me to go up and down. ( I am 177cm, 82 KG).

We had some water problems for 3 nights. There is no water after 12 pm or 1 pm and then water will resume after some hours because they were fixing something in the night, so one night we didn't take shower (imaging we had walked around whole day in 30 degrees in Rome) and one night couldn't flush the toilet after we had showered, and then one night we waited for a couple of hours to shower shower. (water was back at 2 pm i think). So, you might risk the same if you stay there. We have got compensation for night free after complaining this to Airbnb.

Don't count on receiving breakfast there, as they have only few pieces of cookies. But tea and coffee are available.

Last, we couldn't deposit our luggage with the host, so we paid 20 euros in the train station for depositing our luggage. (Remember to check this with the host before booking.) But they were nice enough to give us 30 minutes more to check out, so we checked out at 10:30 am.

In short, this apartment is just a place to sleep thus not good for long period of stay but for a night or two before taking next train, it is fine.
