Luisa's place is great: the location is very central (10 minutes walk to the Guggenheim, 10 minutes walk to the old city centre Casco Viejo, great restaurants right outside), easy to reach from the airport (the airport bus drops you off just a 3 minute walk away), the cleanliness is impeccable, and the welcome by Luisa (and Otto, the lovely tackle), was very friendly. Highly recommendable!
