Fantastic location in the middle of the Sassi!! Cannot beat the views from the various suites! Taxis are also able to drive right up to the hotel, which made for a very convenient pick up and drop off. And the breakfast! WOW! One of the best we have had in Europe in terms the wide variety of local selection and service.
The room was quite large and cozy for a cave. It was a little damp/stuffy, plus the floor had small ants all over the place, but can't really complain about that given you are staying in a cave. As this is also a spa, I was expecting a little better amenities in terms of body wash, hair wash, etc. They do provide slippers though which was amazing on the stone floors. We only stayed one night, so did not get a chance to check out the spa but would have loved to. Would highly recommend staying here!
