Unbeatable location in Madrid’s center. Close to everything on foot and with really good transport connections close to the apartment. Communication was great and very easy. The apartment was quite as expected and with everything you’d need for a short stay (visiting or coming for work as it was my case).
Only down side is that the apartment was not spotless. There was quite a bit of dust on all surfaces.. nothing one cannot live with though.
Overall good value and best location!
