Alvaro's apartment is in the best location in Madrid. We walked west to the Palace, North to Centro, and East to the Prado. The apartment is modern and very clean. Well equipped kitchen. We did not cook but if we wanted to, it had everything we would need. I loved that the bedrooms were on opposite sides of the bedrooms and there are two bathrooms. Gave us space and privacy. Each bathroom had a built in hairdryer. Great that we didn't have to work around who was using the hairdryer next.
Being on the bottom floor was a big plus for me and my friends.
If I go back to Madrid, this is the only apartment for me.
