Honestly one of the nicest AirBnB's I've stayed in - I can't recommend it enough! The place is absolutely massive and can easily accommodate a large group. The location can't be beat - you are right bang in the centre of Madrid yet somehow the apartment is quite quiet and offers a nice place of solitude from all the action on your doorstep. The design of the place is really amazing, the pictures don't do it justice. The host has also thought out and planned very little detail you need for your stay. Honestly I couldn't think of a better place to say in Madrid!
