From the point of booking to our departure, Victor was a great host. The flat itself is superbly located. Almost everything you need is within walking distance, some of the best highlights are just metres away.
It is a stylish space with all necessary comforts and more, and new, really comfortable, memory foam mattresses. We were really comfortable, and noise was never an intrusion.
We stayed 5 nights and didn't struggle to fill the days. Whilst not having the headline "sights" of, say, Barcelona or Seville, Madrid is a European capital city with plenty to see and do, all within walking distance.
Getting around is easy, if you tire quickly, you are never far away from a metro station, and the flat is 200 yards from both Callao and Santo Domingo stations. It's very cheap too; just remember if you are going back to the airport on the metro, there is an extra fare to pay on top of the standard. Don't chance it; they check; but the ticket machines are intuitive, and tell you how much more you need to add to your card to get there.
There are myriad small food shops nearby, and in the basement floor of El Cortes Ingles department store there is a large supermarket packed with everything you could need; again; 200 yards away.
If you're planning to come to Madrid, book here; you'll not be disappointed. Not the cheapest: but you get what you pay for.
