We were so pleased with our stay at Maria's house. It's honestly bigger than expected so just for the 4 of us we had loads of space. The location is superb, right in the middle of everywhere you want to be. The house is incredibly clean and beautifully decorated. Our host who checked us in was incredibly friendly and made some lovely suggestions for dining and getting around.
Our only suggestions would be the Wi-Fi could be bit stronger as it's not accessible from the bedrooms, having a 2nd set of keys would have been handy too.
For those that are worried about noise, it's very quiet once you're inside- we all slept peacefully. Also be prepared to walk up a lot of steps to get to the apartment (a bit of a challenge if you've just walked up the colosseum!)
All in all it was well worth every penny. We cannot wait to return to Rome and book this house again.
