Oscar was very accommodating. We had arrived via train a few hours earlier than our designated check-in time, and he had allowed us to access the apartment to drop off our bags. We had plenty of things to do thanks to the recommendations of places to go/eat as per his website that he referred us to when we booked. The apartment was clean (and the cleaning person had not yet come to freshen up the place after the last guests left) and bright. The apartment was a short, five-minute walk to the Prado, and a 25 minute walk to the Palace and Royal Gardens. We had everything we needed for our short stay in Madrid, thanks to Oscar and Vanessa.
