Martin was an excellent host. He was available for all additional info and services and we had all the privacy we could imagine. Of course, none of above mentioned services and extra info is needed because description of the apartment given at airbnb pages is absolutely correct.
Thanks to Martin and his friend Zoltan who recieved us and gave us a few extra usable tips about Madrid we had an excellent week in Madrid.
Martin even provided us a late check out and and Zoltan offered a transport to airport.
And the most important: everything was just as described at airbnb pages.
