The communication from the moment we booked and up until our departure was swift and Alex even recommended us some places in the area. We also got a drink at the ice-cream shop below the apartment upon check-in, which was a very nice gesture. The idea of the Maker House / Builders is really interesting, and I would recommend anyone to stay at this special apartment: The bed is really comfortable, for the two of us, there is lots of space and it is fun to see all the design details in the apartment. It is perfectly located in the center of Madrid, which unfortunately also means that there is a lot of noise from the street below. So if you are looking for a quieter stay, this might be a nuisance, but for us it was okay, as we had earplugs and enjoyed the lively nights of Madrid and being so close to everything.
