The apartment was clean and as described. It's in a good neighborhood, about 15 mins walking from Plaza Mayor. Gran Via is 3 minutes. It's close to the Royal Palace and the stores, parking and metro.
When we drove in Madrid it was an extremely busy Saturday night and we got lost close to the loft. We called German and he came to meet us right away. Very, very nice host! He helped to carry our bags to the apartment.
He got candy for the kids and wine and water for the adults.
I can't write anything bad about the place.
What others had mentioned before (slow wifi and low pressure in the shower) were true, but we could work around it, it wasn't a big deal.
