I would highly recommend Irene's apartment. It is within walking distance of the city and the sites, and only 4 minutes on foot from Maria Zambrano where there is also a well stocked Mercadona as well as transport links and car hire!
Irene's communication was good and Marina, who welcomed us, was delightful! Muy genial! The apartment itself was nicely furnished and had air con in each room (a must in the summer!).
Irene left us a bottle of rose, which was a nice touch too!
We had an issue with the power cutting out, but Irene was quick to communicate and the issue was resolved.
Marina booked us a taxi for our flight which was at an awful 5am and this was so helpful at that early hour.
I would have no hesitation staying here again.
