Alfonso's apartment is wonderful! My wife and I stayed there for an entire month while we were working in Madrid. It's a great place to work from, even for two people, since it has an upstairs and downstairs to create private spaces. The place was very clean when we arrived and cleaning supplies (broom, vacuum, etc.) were available for us to use during our stay. The space is very functional, and aesthetically pleasing as well. The location can't be beat. La Latina is a great, lively, neighborhood, but this apartment is on a quiet street so your stay will be peaceful. You have your quiet home when you need it, but there are bars, restaurants, a market, grocery stores, etc. all within a few blocks. Alfonso is a great host, too. He's very communicative and friendly. He lives nearby and we'd see him in the neighborhood often and say hello. I'd highly recommend this apartment!
