Helen and Martin are amazing hosts and really know how to make their guests feel welcome and comfortable! Their Madrid flat is perfectly located (so much to see, eat, and drink in very near walking distance), clean, and has everything necessary for a wonderful short or long-term stay (the fridge, washer/dryer, french press, etc. are major perks). Fave part of the space: the two french doors/windows that open to the terraces. They let in a lovely breeze and sounds of the city (each afternoon a local played Spanish guitar in the plaza below the flat — it’s quite special). Apart from the space, Helen and Martin are simply great, friendly, communicative people. They told us all about the city (and annotated their map) and went so far as to make us a dinner reservation at one of their favorite restaurants (that meal was one of the highlights of our stay in Madrid). We honestly cannot say enough good things about these two. If you want a memorable Madrid experience — stay here!
