Our stay at David's apartment in Madrid near Gran Via was absolutely amazing. In terms of location, if your goal is to see everything that central Madrid has to offer, you'll be in the perfect place. It's one block from Gran Via, on a much quieter street. The neighborhood has plenty of nice shops, bars, and restaurants, and feels extremely safe. There was never a point during our stay when we were more than ~25 minutes walk away from our destination in the city. In terms of the apartment itself, it is just as advertised. The terrace is beautiful (although we visited in November, so it was a bit too cold to use it much), and the apartment is impeccably decorated. David was extremely flexible around check-in/out for our stay, and overall was a pleasure to work with. I would definitely stay here again for a future visit to Madrid!
