We enjoyed our stay at Mely's place. It's incredibly clean and check in was really easy as Mely greeted us in person and explained everything. The location is really central and just a few minutes walk to everything - shops, metros, restaurants and of course the Plaza Mayor is literally right there. It does get a tad bit noisy in the early morning with actions around the plaza but it didn't really bother us too much because we worn ourselves out everyday with our walking and plans. Overall this is a great apartment!
