René is not only the best host we've ever had, but also a great local advisor. He gave us tips into navigating through Rome and having the best from our time there. Advice on queues, routes, locations and literally EVERYTHING a first time visitor should know, he had for us, even a map with landmarks.
With this being said, location of guesthouse as well was very good! Near from the colosseo and around 15 minutes walking from all major attractions in Rome. We only took one metro to the Vatican and started walking from there (as René suggested).
Place is very pretty, has an cute small but useful elevator and building is very quiet, extremely clean, and we were provided clean towels every night.
Easily the best airbnb we've ever stayed at. Would try to visit again and my first choice to visit Rome from now on.
