Patricia's apartment is well kept and better equiped than our other lodgings in Spain. She and her team take good care of the apartment and make special efforts to sanitize it in Covid times, going so far as to provide a small kit with cleaning consumables (like dishwasher tabs, sponges and towel).
While Las Ventas is not very central, the apartment is well connected. Metro lines 2 and 5 (as well as several bus lines) were within short walking distance and lead to most relevant landmarks and interesting districts of Madrid. Atocha (Madrid's most significant train station) and the airport can both be reached by car in some 15 minutes. The Las Ventas market, which is probably not in the itinerary of many tourists but is much more modern and less crowded than staples like San Miguel, is half a block away and worth a short visit. Located on the 10th floor, the apartment itself also offered a good view of the surroundings.
We found a couple of minor defects in the apartment, but Patricia reacted promptly after we reported them and sent someone on the next day to fix some of them. The only point that remained puzzling was the fact that, sometimes, the temperature of the shower would suddenly drop (despite the fact that, as we were told, the warm water supply was not restricted nor shared with other apartments). Turning the shower off, waiting several seconds, and turning it on again served as a workaround.
We think heating could be more powerful. We kept radiators operating at full power in both bedrooms and the living room, but the rooms barely got warm. The one in the bathroom worked well.
