The apartment was exactly as we expected, quite small but comfortable and very suitable for 3 people thanks to the fold-out couch. It's very conveniently located, a little outside the barrio de Santa Cruz but this was even better for us as we could avoid the main tourist crowds and it's right next to where all the real fun takes place: the Alameda de Hercules.
Rosa didn't respond to any of our messages, so we had no idea whether there would be someone to open the door for us when we arrived. Fortunately someone was, but we were starting to get quite worried. Also, the shower wasn't very clean with a lot of mould. But otherwise everything was perfect and the family, who live next door, are very nice people!
