I visited Oasis Day Spa in San Carlos last weekend with a friend. They are located conveniently in down town San Carlos with ample parking. Our experience was above and beyond our expectations. I received a facial from the owner and my friend got a full leg wax. The prices are reasonable and the service was excellent. We will definitely go back. The owner told us that they just got ceritied as a green business which is even more reason for us to support them.
