We stayed at Juanfri's and Emma's home over the weekend; they have a really nice furnished apartment, around 15min by bus from the beach. It also doesn't take long to the city center, unfortunately the metro closes during the night, so be carefull when you want to go home after 11pm. (Taxis are cheap though :-) )
Communication with them was easy, although we got our check in time really late...
We had some problems with the hot water, but hopefully that will be fixed before the next guest comes.
We would recomment the apartment :-)
