Simple functional apartment. Great location. You got all you need, good AC, TV, wifi, etc.
I really enjoyed the stay. The double bed is great. It's firm but soft at once :). The building feels very safe. Fer is a great host and cares for you. Most central spot possible in madrid... Isnt it also called point zero of Spain? I don't know but I tell you go for it! ;) I was the only one guest so I had plenty of space.
