Alberto is a fantastic host: he was waiting for us in the shop he is working in and came with us in the flat/attic explaining the rules and the main interesting sites to visit (giving us some excellent suggestions on where we could have dinner as well).
The flat is very clean and quite and very well furnished; it makes you feel at home, it's got everything you need plus it is within walking distance from all main interesting sites in the city and very close to the metro as well.
Some nibbles and good wine were waiting for us as well in the flat!
What an amazing experience, for sure we'll come back at his place if we're coming back to Madrid!
Thanks again Alberto
