Location, location, location...This apartment is in the perfect spot to explore all of Madrid...Great for walking and very close to the metro...The noise level, considering it's in the center of things, was pretty minimal, in terms of sounds coming from other apartments or the street. That being said, it's always a safe bet to bring earplugs just in case. The space itself was very clean and sparse, yet cozy at the same time. It has a great kitchen, which we used a lot, since there are several large supermarkets close by. Communication with the hosts was always timely and they let us leave our bags early (as our flight got into Madrid early in the morning). But it is important to note that there is a shop where you can lock your bags up a couple of blocks away, so that's another option if you arrive very early. The hosts also arranged for a taxi at check-out time (as Uber traffic was a bit sparse in the area that early in the morning), and that worked out perfectly. All in all, it was a great experience and I would highly recommend this apartment for your stay in Madrid!
