We had an amazing stay at Almudena's apartment. The place is gorgeous, sparkling clean, warm (it was cold in Madrid early December) and has everything you might need for a short or long vacation. Location is unbeatable - you can walk everywhere, plus metro and buses are within minutes walk from the apartment, if you choose to use public transportation. Atocha station is less than 10 min walk and from there you can get to the airport or take a train to other cities in Spain.
Almudena kindly allowed us to check in early and check out later to accommodate our flighs schedule. Communication with her was easy and pleasant.
Thank you, Almudena!
