We had a good rest overnight in comfortable bed. Our lack of Spanish caused us a little effort to find the place. Good location, only 5 subway stops from "must see" Museums in Madrid.
The professionally prepared photos in the listing created some let-down - only seating was 2 wooden chairs plus small table, no sight of any lounges, the window looks into a light-well with view of opposite blanked windows, etc.
Appreciate Charo's effort to get up at 5.30 am for our transport to the airport.
