Great location- only a 20 minute walk to either the Vatican or the ruins (located about halfway between). There is a bank machine and grocery store within a 5 minute walk, and lots of small restaurants nearby as well.
Perfect for two couples traveling together- two bedrooms, with two full bathrooms. The kitchen is a bit small, but other than breakfast- we did not use it anyways- so not a big deal.
The host was very helpful and responsive when we had a problem with the keys, and rescued us (from our own stupidity).
Compared to most other places we stayed at while in Italy- this location was very quiet, which surprised us, given its great location. And this place had the BEST mattresses by far. Real quality beds! Big thumbs up on that!
