Arnaldo is an awesome host! He sent clear instructions for the self check-in and offered that we leave our luggage at 11:30 even though the earliest check-in time is 14:00. And the apartment was actually completely ready by the time we got there! The place is nice, spacious, stylish and clean. We didn't cook but I think the kitchen had everything that is expected. Would probably consider staying there again if we ever visit Madrid in the future.
