Pablo was responsive to all our queries right from the start. He was flexible with our arrival time, which was very late, but he still greeted us with a smile!
The apartment is plenty big enough for two people with all the facilities you need, fully equipped kitchen, hot shower, comfortable bed and good wifi. The local is excellent and you can walk to most places easily or the metro is just a short walk away. There's a supermarket literally 2 minutes away and a couple of good restaurants just as close.
We were there over part of the Easter weekend so Madrid was busy with lots going on but it was still quiet in the apartment. It is a bit of climb up to the fourth floor but you only have to do it once or twice a day, good exercise!
We would definitely recommend Pablo's place for a convenient, quiet, good value stay in Madrid city.
