Claudia is a wonderful host! Fast replies, let us come and drop off our bags even though the flat wasn’t ready. Great location, clean and modern flat. I went for a few nights with my mum and had a great time for my first time in Madrid. Everything is within walking distance 10-15 mins max. The only thing would be that you are in a city so noise from street is to be expected! Would return to Claudia’s compact clean and stylish apartment!
