I stayed with Ricardo while studying at a local Spanish school and for me the flat and room perfectly met my needs. Ricardo is an excellent host, very informative and friendly and fortunately his English is much better than my Spanish!
The room itself is good for studying at the desk if that’s what you need, and the bed comfortable. There was a bit of noise at night (although no bars or restaurants near enough to be audible, people sometimes make a bit of noise walking down the street at night, but I found that closing the window let almost all the noise out). The shared bathroom was very clean.
The area surrounding is buzzing with lots of small bars, cafes and restaurants. There are tourists around but it’s certainly not a tourist district so if you want to stay somewhere less touristy this is for you. Having said that, pretty much all of the main tourist sites are easy walking distance, but the metro station is also very nearby if you need it. Recommended!
