Though unassuming from the outside, Casa Candelario is a treasure! Great kitchen, huge master suite, lovely patio. The owner, Michael, was super friendly and was over with the key in a couple of minutes (when we couldn't find it); he also gave us a quick tour of the patio and gas grill. The location is great, too....about 15 minutes' walk to the plaza, and about 7 to Casa Chimayo (great NM restaurant).
There are also a lot of little touches, from the beautiful polished plastered walls to the granite counters in the kitchen to gorgeous native pots to the enormous master bath. It was also spotlessly clean. I'd come back in a heartbeat...much better than staying in a big hotel.
