The flat is awesome, much bigger than it looks in the pictures.
Well located, everything is clean and new and it's a real appartment with life, not a ikea-quick-furbished one.
Carlos was nice and available!
And the location well, Super center! We did everything by walk: malasana, palacio real, latina, rasto, retiro ect.
I really recommand this place to stay to discover Madrid.
Thanks for everything Carlos!
