I was travelling to Madrid for 3 weeks and was looking for a place that would have a good connection to the city centre and green areas for running/walking nearby, and all of that for a reasonable price.
Luis' & Ana's place ticks all these boxes. The description on the site matches with what you get, it has everything you need for daily life. Also the rules for sharing common spaces are sensible and easy to follow.
Luis & Ana themselves are very friendly and attentive, you can always ask them if you need something. In my case I got shown to everything I needed to prepare meals in the kitchen, and got some advice on ways to get around in public transport. Luis also notified me when there was going to be some louder singing in the house, and regularly asked for feedback about anything that I thought could be improved. And it was also nice to just have an occasional casual chat.
I had an excellent stay at Luis' & Ana's place and I can wholeheartedly recommend it to others as well.
