Great stay! Max made sure we had everything we needed. Had a minor issue with water not getting very hot, and he had a plumber in the very next day to fix it even though I told him it wasn't bothering us and it was fine if it didn't get fixed while we were there.
The location is very convenient. There is a front entrance and a back entrance, we found the back entrance to be the one we used pretty much every time because there is a metro station across the road and a short walk to the right, as well as several bus stops within walking distance. Above the metro is a regional train that connects to trastavere, which isn't serviced by Metro, so this location was good for visiting that area as well. Major sites/attractions took 30 minutes or less by Metro or bus, for the most part, and the price is much more reasonable than places that are much closer- personally I'd rather save my money for my trip and I don't mind taking a metro to the colosseum!
The neighborhood within walking distance has several good restaurants and grocery stores, as well as cafes for coffees and pastries. The apartments were quiet, we felt safe the whole time, and everyone we saw was friendly towards us.
House rules were reasonable as were check out duties. Probably the best host we've had in our Airbnb experiences. No complaints at all, would definitely stay here again and recommend to anyone.
