Overall, the experience was very good and we enjoyed our stay very much.
The location was perfect. Close to the center, next to the Gran via, lots of nightlife and restaurants around.
The apartment itself was very modern and clean. We loved the window that crossed the entire room overlooking Fuencarral street. There were lots of nice details as well, such as water bottles, a tote bag, lots of plates/glasses/dishes.
Both, my partner and I worked from the room between 8am - 4pm and we both had separate tables/chairs so that was nice.
10/10, would recommend!
