Alfredo and Ricardo's place was perfect for spending a few days in Madrid. It's about 5-10 minutes from Plaza Mayor and also the metro station. We didn't have the pleasure of meeting Alfredo or Ricardo, but communicating with them was very easy (responses were always prompt) and check-in was no problem. The place is nicely decorated and feels like home. Alfredo and Ricardo put out a bunch of tourist maps and coupons as well as some wine and gummy bears, which was nice! Yes, you do have to walk up 5 flights of stairs, and yes, the ceilings are low, but neither of these things were a problem for us. Overall, it was a lovely place to stay and a good location and we would recommend it!
