TLDR - Really really wonderful experience and would highly recommend it to anyone looking for a place in Madrid. Would definitely come back again to the place when i come back again.
Firstly - the place is just perfect. Like really perfect in any way. Value for money, location, safety, cleanliness, wifi, television, space, beds, air conditioning etc. Not much to say about it, best airbnb iv'e been in.
Other part is Matias which was not only super welcoming from the start, but also really really helpful along the way and even a bit after :P
So really, if anyone reading has any doubts about this place, just book it immediately and there is no way you will regret it
