Everything was perfect!
Jason met around midnight in the apartment after our late flight arrived with no problems. We communicated in advance and we had all the necessary details.
The apartment (Queen Mary Madrid) was without any doubt the most spectacular apartment we stayed in and it is even better than boutique hotel. It is even better than the pictures, everything is brand new and the decoration is stunning! The apartment is very big so you have a lot of space. The kitchen is well equipped (even Nespresso machine!). The living room is spacious. The main bed room has huge closet and shining new shower. The second bedroom has also a private bath so it is very useful if you are more than one couple.
The location is superb! 10 Minutes to Plaza Mayor, and very near you can find a lot of pubs places to hangout at night!
Jason himself was very responsive and helpful - even at 1 A.M. when we discovered we need more blankets and he got us more blankets immediately!
Summary: Very recommended!!!
