Great place in the Malasana district. Everything is new, clean, white, and the place has nice windows with mechanical blackout shades.
Hot water is sufficient, powerful sink, laundry machine, dishes, everything you will need for a trip to Madrid. The location is excellent, in the gentrified/gentrifying alternative Malasana district with lots of hip bars and good restaurants nearby. Everything you need to live well within a couple minute walk. About a five minute walk to the Tribunal and Gran Via metro stations.
Highly recommend this place. The host is excellent and genuinely loves Madrid.
The only negative I would note is that if you are a light sleeper, the walls in the entire building are not soundproof. You will hear doors opening and closing and your neighbor's television.
