Our trip to Madrid was awesome especially cause we got to stay in Sergios apartment which is centrally located and close to everything including 3 different train stops, Peurta delSol, Plaza Mayor and for a longer walk the Prado or Royal palace. so it's so easy to either walk or take the train as needed for time and comfort. The apartment is on the 4th floor and it is a walkup. There is enough room for 3 people, not large but cozy. Hot water and washing machine, a/c all working. It's on a slighly darker and quieter street at night but don't be afraid. Easy to sleep as it's very quiet in the home. No wifi but Sergio tells you how to use his computer. Turn on the hall light to see up the stairs at night. Great place.
