The owners -a sympathetic couple with a teenage son and daughter- are really nice and hospitable and will go out off their way to make you feel comfortable and at home. Breakfast and dinner is served on the patio looking out over the garden. Very peaceful and something woth taking time for. Not just to relax but also because the meals were copious and the lady of the house is a damn fine cook. (If you ever happen to stay there and they ask you in the morning what you would like for dinner in the evening, just reply with: "Surprise me.")
There are many 'casas particulares' in Santa Clara, but this beats all of the ones I stayed in hands down. If you're planning a stay in Santa Clara, try this place, you won't be disappointed!
