Sergio and Elena were great hosts !
It's easy to communicate with them.
The flat fit almost perfectly the description: it's clean, well equipped and in great location to visit Madrid.
Just one thing: it wasn't as calm as we expected (which was one of our top criteria) because the flat upstair is not very soundproofed then we were disturbed a few times during the night.
Apart from that it's a great flat for the price !
