The apartment is in an amazing location, tucked away in a side street. The view from the shared rooftop terrace is wonderful especially at night when the cathedral is lit up.
The downsides for us were the tiny kitchen with limited equipment. With so many good tapas restaurants in walking distance this wasn't too much of a problem but a few more basics would have been useful. The 'magnificent balconies' were disappointing as they are actually only about 40cm deep so standing room only!
Carmen kindly organised transport to and from the airport which I would recommend.
