Excellent value. Well located, and the bike really helps if you want to get to the centre in a hurry. Plus it's a great ride running alongside the river. However, it's an easy walk too. The room is big, lovely and quite cool considering the hot summer temps outside. The ceiling fan is a great help as well. The whole apartment is lovely: clean and fresh. Above all, it is really quiet and peaceful.
My hosts were unfortunately absent the whole time I was there as my visit coincided with their holiday, so I'm unable to say how it would be if you were sharing with them. I was alone and only had two days notice, so it was sometimes a little difficult, especially as I don't speak Spanish. I gather that the hosts are quite busy and so it's possible there would not be much interaction even if they were present. If you're a couple or you are Spanish and know your way around, this would be no problem.
There were recommended bars and restaurants on a list, but most of these were closed for August holidays. I was also surprised that almost everything including the main shopping area closes down on Saturday afternoon as well as Sunday. If the hosts had been around, this is the kind of simple day to day information that would have helped. Although they were available by airbnb messaging, it is not the sort of question you would know to ask.
However, overall, the place was great and I would highly recommend it to a couple or Spanish traveller in a heartbeat.
