Daniel's place is a rare find. The location is superb, very centrally located. At first I was worried about having to pick up the key somewhere else, but it turned out to be very close and convenient. The video clip introducing the apartment and how to use all the equipment should make life easy for both the host and the guest. In addition, Daniel added a personal touch with his list of extensive categories of local tips.
We stayed 3 nights and had everything we needed there. Communication was easy and fast. We didn't meet Daniel, but he seemed readily available online before and during our stay. Will definitely be our first pick next time we visit Madrid.
