Joaquim y Natalia’s place has the most central location in the heart of the old city. Minutes to Sates and el Divino Salvador church. Not to mention supermarket is right round the corner, and lots of tapas bars nearby.
The hosts have been most organized in providing a list of searchable recommendations regarding food, shopping etc online, to satisfy most needs.
Apartment is spacious for lone travelers like me, and can fit two to three people easily.
