The apartment is beautifully decorated and is very central between the cathedral and plaza de la constitución. Seb gave us a very warm welcome with many tips on what to see and where to eat. We had a fantastic few days and really loved the apartment.
Only two small things that I would note if you are looking to stay here is that the smaller bed (140cm) is actually a fold out sofa bed, and secondly if you turn a lot of things on the electricity can trip (it's an old building and we had instructions on how to fix it but it can be a minor inconvenience!)
