We have been to SS several times and without doubt this is the best situated place we have stayed. Very authentic and comfortable place. Santiago gave us an excellent introduction to the apartment and surrounding places to eat/see/visit. The accommodation was as described and perfect for our group.
Easy walking distance to the old town with tapa bars, the Concha beach and downtown shopping. Secure underground parking is easy within 10-15min walk in the Gros area over the 'lighthouse' bridge.
An excellent choice for your stay in SS.
