Great studio, a stone throw away from placa de la constitucion. The only catch is that it's on the 4th floor without a lift, price to pay to stay in a historical building.
The floor is shared with 3 other similar studios.
Clean, good cooking facilities, tiny balcony with processions during Semana Santa, in the heart of the lively historical city, great recommendations by Arantxa, washing machine, French doors separating the bedroom from the kitchen/bathroom (no fridge noise at night), real comfortable bed (not a sofa), surprisingly quiet at night outside as it is a pedestrian area, just a few cleaning crews with some loud machinery that were somehow fascinating to watch.
Altogether a nice 15 minutes walk to the Malagueta beach, 10 minutes to the nearest train station, 30 minutes to airport door to door.
The hardest part was to leave and go back home.
