tho the room is as described, there're a few things you might know: there's no natural light in the room, and the lamp is so soft you couldn't even read a book.
also, if you're taller than 1.70m, you won't fit in the bed.
for the rest, the room and the rest of the house are very clean and tidy, and Cruz the host responses politely and quickly.
if what you need is a cheap place to sleep in the centre of madrid and you don't care about anything else, this is your airbnb.
