Arnaldo is simply an amazing host. Our trip started on high note and sadly had to end sooner than expected due to the uncertainty in worldwide travel because of the covid-19 . Arnaldo was so supportive of us as we tried to get home to our families. I can't recommend this place enough! It is modern, everything is brand new, clean and tidy. The location is amazing, as you are literally 1 minute walk to the Atocha train and bus station. The security to the building is also top notch. You are given a code and a key. The check in instructions could not be more clear. Arnaldo has everything covered! We are so happy with our stay in Madrid. We hope to be able to return to Arnaldo's place one day when things get back to normal in the world. Highly recommended!
