Martin's place is mega central and very close to the plaza merced, the theatre and a big supermarket. It's equipped with all that you need and has a super comfortable bed, lots of closet space and a nice kitchen.
Martin was super helpful during my stay and gave me a lot of tips of renting houses myself in Spain (which was the main reason for my visit).
100% recommend this place to anyone! Especially when you want to live very close to the city centre and want to sleep on a super comfortable bed.
