The house is perfect for a couple. You get what you pay exactly!
I would definitely point out the good location of this house. 15 min walk to colosseum, near termini (5 min) with a lot of supermarkets near by, 10 min to Pantheon or Fontana di Trevi.
The only "less good" thing to point out is that the vents outside make a great noise and sometimes you hear people from the Pub that is near this house.
We had a beautiful stay and we definitely recommend to all. Hope the next time i will go to Rome this apartment still exist.
Regarding the hosts, there are a lot of them but they are really fast to answer to your questions. Always available to help you out with something. Umar received us at check in and he is a super nice guy!
