I had a really Nice Stay ! The Location was perfect, it was only 2-3 minutes to the Metro Stations Bilbao and Tribunal. There was also a big supermarktet next Street. Bars, Club and Restaurants are also only a few minutes away (in malasaña). As already Stated in the other Reviews, The Communication with Klevi was very uncomplicated and he replied really fast ( it was mainly via WhatsApp).
During my stay, it was 36 degrees in Madrid and the room was accordingly warm at night, as there was no fan, for example, and my room facing the courtyard allowed little air circulation. This is the only thing that could be changed. However, the room was very large and bright, there was a large bed and also a large towel for me. There was also a mirror, desk and closet. I can really Recommend this room to other visitors :) Thank you Klevi :)
