The apartment is overall good for a short stay in Madrid. It is very centric, close to restaurantes, the metro, monuments and markets. It was surprisingly not noisy for its location. However, I was a bit surprised that although air conditioning was an amenity included in the listing, at our arrival we were told we couldn't use it because "people in Spain don't turn on the AC until later in the summer". We had to rely on a mediocre fan. Thankfully it didn't get too hot in Madrid until after we left but there were definitely some nights that weren't as "cool". The only other ventilation was opening the balcony door, which I found unreliable because it made us paranoid about bugs potentially coming in, even if none did.
