Emilio's flat is a true gem in the heart of Cheuca. It's super spacious and well-appointed. The flat is mostly underground and you do hear some street noise but that's part of the charm of being so central within Madrid. Furnishings are new and very stylish.
A note on the kitchen; there is no oven and a hob with only two burners so be mindful of that if you're looking to cook often. I ended up eating out every day so it wasn't an issue, but if I had wanted to cook I might have found the kitchen quite limiting.
