This was my fourth trip to Rome, and one time I stayed for a month in an amazing apartment near by thats no longer for rent. Every time I see a bad review on something with mostly good reviews I'm suspicious. That said, here's my experience.

Pros:
- Great Location - close to St Peters, 10 minute walk to the metro, safe neighborhood, near lots of restaurants.
- Cool view of St Peters
- Quiet Street

Cons:
- Thin walls. You can hear the people above you very clearly. (And I would assume vice versa) It was loud enough to make it difficult for me to fall asleep.
- Didn't interact directly with Jane. This might seem like not a big deal, but it was weird that she's listed on the listing, but its really another person running it. He spoke english well enough and was friendly, but it was weird he's not really mentioned on the listing.
- No hot water. We noticed it as soon as we got there and texted Alessandro. He came over and tried messing with the water heater, but wasn't able to fix it. Then he said it would be fixed the next day. Each day we were there he told us the person would be there the next day. (This is a bit how Italy works, but hot water is a big deal, imho) So we ended up going 4 days without hot water. If it took one day to fix, I would have understood. Personally though if it was me running it, I would have made sure someone fixed it in a timely manner.
- Really hard bed. I didn't try the other bed, but the one I was on was like a board. And I usually like a bit harder of a mattress.
- Limited control over the heat. When Alessandro let us in, he told us that the heat was "automatic". I assumed that this meant that we just pushed up or down and it changed the temperature. After messing with the thermostat for quite a while, I figured out how to change it, but it seemed like it would jump back to the default every few hours. Perhaps there was a way to hold the temp, but I couldn't find it. (I'm a software developer, so I'm usually pretty good with technology) That said, I should have asked about it.
- Heat is noisy. It took us a while to figure out what the source of the noise was, we thought it was outside originally. Nothing you can't tune out, but I thought I would mention it.

Overall the place was fairly clean, easy to get to, and large enough (though a bit on the small side, it was tight to get around the table for example). The fact the hot water never got fixed is enough to make me not stay here again.
