Nice and spacious apartment with a lot of privacy. The apartment is located on the top floor of the building and the only apartment on this floor. There is a nice terrace.
Antonio is very friendly, he waited for us to arrive at the apartment. We had to leave early to go to the airport, so we could just leave the keys in the mailbox.
Also a big plus is the very well equipped kitchen, with a large fridge, freezer, furnace, water boiler, toaster and espresso machine.
Also, having fast WiFi available was great.
One drawback: the shower turns cold after a few minutes.
Location: the apartment is not located in the touristic centre of Madrid, but it's only one metro station away and Lavapiés Estación close by.
