My girlfriend and I stayed here for 2 nights recently, and we found the apartment was very spacious, well-equipped (perfect for a family). Although we never got to meet Rocio or Ward, they were great hosts, prompt with communication, very friendly and offered heaps of helpful info.
We enjoyed the selection of DVDs and very comfortable lounge area! We did have a bit of a problem with connecting to the wifi in some rooms though.
In regards to the area, there's a nice bakery and a small grocery store nearby, and it is about a 10 minute walk to the train station, and then 15 minutes on the train to get into the main tourist area. Coming home on the train late at night we did feel a little uneasy at the station though unfortunately, with groups of men loitering around.
