The apartment is phantastically centrally located, in walking distance to lots of sights and also the transport hubs we needed (bus stop from the airport, Retiro train and bus station). Lots of restaurants and breakfast cafes virtually at the doorstep. Martin is a very responsive host, and we clarified everything about our arrival up front. We are especially thankful that he flexibly accomodated our check in and out times. The apartment is quite large and had everything we needed. A highly pleasant stay! We highly recommend Martin as a host and staying in his apartment!
