I have stayed at this flat one other time and it is very good in terms of location, if you want to have a real taste of Madrid. Also it is very well decorated and it has everything you need for a good holiday. The only thing is this time, it was a huge stain in the wall, I think it was from some broken pipe. It was smelling humidity although they have the window open when I arrived. It would it be very nice if the owner would say something before he accepted my booking, or at least offer me a discount if I would decided to stay there at the end. I find it it was no very nice to hide information to guest.
