The welcoming was great. I was late by one hour and still, I was being welcomed with a big smile. I would recommend this studio to any traveler/couple who wants to visit the centre of Madrid in foot. You've small shops and Bars near by ( so many that you'll have a headache choosing where to have a drink). Regarding the studio, you have absolutely everything you'll need for your stay (even Netflix :).
It's definitely a place where I would stay in my next visit to Madrid.
