We stayed only one night at Pilar's place as we were only in Madrid for under 24 hours. It's location is ideal as it's between the airport and downtown. As other reviewers have said, it's not a big unit (it's an apartment that has been separated into two different units) - but it is well-equipped with everything you'll need and has modern decor. Pilar was a wonderful host - always available to help with any questions! Thanks for everything, Pilar!
