Our two-week stay here was exceptional. You can't get more central than Puerta del Sol, with metro stops all around and within walking distance from Gran Via shopping, Retiro Park, museums and tons of restaurants and bars. There is a 24-hour Carrefour Express supermarket a block away, a Corte Ingles supermarket and department store a few blocks away, and a beautiful new yoga studio (Numen Yoga) a five-minute walk away. The apartment was even nicer than we expected. It seems like it was renovated recently because everything feels very fresh. We chose this location because it had easy access to a WeWork via metro, but the kitchen area in the apartment was so nice and the wifi was strong, so we ended up just working from there. There is more light in the living area than we expected with two little dormer windows you can open to see the sky above and street below. The bed (I'm pretty sure it's a queen) is super comfortable (there's a shaded skylight above the bed, but not a black-out curtain), ample closet space (with a shoe rack and lots of hangers!) and a TV that connects to Netflix. The AC works very well, there's one in the living area and the bedroom. Everything was sparkling clean when we arrived and Zulma walked us through how to use all the appliances. There's a slim dishwasher; microwave; toaster; Bialetti coffeemaker (I wish there had been an electric kettle), oven & stove top with a nice set of pots, pans, knives and other necessary cooking utensils (plus a wall of cabinets to store food); and washer and dryer units (a luxury we took full advantage of; although, the dryer isn't super effective, but there's a drying rack and an iron and ironing board). The washer broke during our stay and Carlo, the lovely apartment manager had a new one installed the very next day! He was so nice, respectful and communicative. While the washer was being installed he gave us great tips for things to do, including a visit to the Hotel RIU rooftop, which has an incredible view and we were so glad we went. The bathroom was spotless and I loved that there was a rain shower and handheld combo that had great pressure and hot water, and there's a storage cabinet for toiletries. They left extra sets of towels and sheets. There were also staple items in the apartment like olive oil, salt, lotion, shower gel, extra TP, a hairdryer, nail polish remover, dish soap, dishwasher cubes, bags, etc. that were so helpful to have upon arrival. They gave us two sets of keys, which was convenient for coming and going. Our flight was canceled due to a hurricane and they were so helpful in extending our stay last minute. I would come back to this apartment in a heartbeat. It made our stay in Madrid so comfortable, productive and fun. By the end, we felt like we lived there!
