We really loved staying at this place! David was very responsive if we had any questions and was kind enough to meet us at the apartment at 9PM on a Sunday night after our flight was delayed and he was also great resource for recommendations. The place was very clean and in a great central location to everything that we wanted to do in Madrid. We didn't utilize the Metro as we mostly walked everywhere (for long trips we used Uber) so we can't speak to that experience, but there is a Metro station very close by. The apartment is not huge as this is European style, but it is very stylishly designed with extra touches that helped maximize the space that was there, so it never felt we were tripping all over the stuff we brought with us (like lots of shelves & hooks throughout, and great closets with hangers/drawers/shelves etc). We were very comfortable as a party of 2 sleeping in one of the 2 bedrooms, and you could easily have 2 more people in the other bedrooms. The bed linens were white and crisp, and both the pillows and mattresses were very comfortable memory foam. The towels were fresh and clean and we had enough for the 2 of us, and the shower was super nice. In the mornings, there are several places around where you can get a coffee/pastry, which is great! For those coming from the US and have never used a combo washer/dryer before, just plan for the laundry to take longer than what you might expect, as it is a different mechanism in these types of laundry appliances that what is standard in the US for standalone washers & dryers. Also, reminder that this is on the 3rd floor, so prepare for carrying your bags upstairs and just pack less clothes and do laundry instead. We would definitely stay here again if we are ever in Madrid. Thank you, David!
