We had a great stay in Ricardo's loft. It is well situated between the older areas of the city such as the Cathedral and Mercado Central (market), the park with the Museum of Science and Art, and the harbour and beach areas. We never waited more than a couple of minutes for taxi's.
The loft is very clean and well-appointed with everything you need and compared with other places we have stayed has good space. Ricardo is very helpful and accomodating. I strongly recommend this one.
