Ruben was very flexible for our check-in and check-out times, letting us leave our suitcases past 4 pm, and agreeing to come later to receive the keys. (Unfortunately, our ride to the airport cancelled at the last minute, forcing us to leave immediately after, to avoid missing the flight home, for which we apologized over the phone, since this situation was beyond our control).
Regarding the apartment, it offers very basic amenities, enough for a short stay. Great location -although a bit noisy due to the street traffic - good wifi, very hot water and comfortable mattress. Several items could be improved, including the ac system (we were provided with two electric heaters), adding handles on both sides of the entry door - making it easier to open and close, the paint on the walls - which was peeling in some areas, and providing an extra blanket to the bed, since it was a bit chilly at night. These would make all the difference.
