Wonderful, charming space! We used this as a base for a Puglia road trip as it was fairly central. We spent most of our time out of the trulli, and we didn't have the best weather, but I wish we got a chance to use the outdoor amenities. The place was clean but it does get damp there. The trulli weren't too cold at night either.
The driving directions were a little tough to follow and you lose some cell service getting closer to the trulli, but if you type in "Trullo di Raffa" in Google Maps, that will get you there! Also be sure to arrange with the housekeeper Manuella on WhatsApp beforehand.
