Ruben and Leticia were excellent hosts, quick to assist and handle any and all annoying questions that I came up with :-).
If you don't know the area, Malasana is super hip, but there are all kinds of people running amok. We have a small child and found many cafes with playgrounds safely nearby for our little one to play (while we drank/ate).
I would be happily stay there again,and highly recommend this very centrally-located apartment if you're looking for a fabulous time in Madrid.
