Stayed two weeks at Marcos place & have no complaints. Apartment is as advertised, it is a short stroll to all attractions in a super convenient location .
The apartment is clean & styled nicely, very comfortable beds and crisp white linen.
The check in process is easy , just ensure you download the app as instructed, staff are on hand at all times and assisted us with luggage storage on our check in day.
Really happy with our stay, it made our time in Madrid perfect !
