I cannot say enough great things about the amazing stay I had at Laura's apartment. I spent a week in Madrid for a wedding, and stayed in the apartment by myself - it's the perfect size for a single person or a couple. Many times, apartments in Spain have weirdly tiny showers, but this one was perfectly sized. The apartment was sparkling clean, all amenities worked flawlessly (including air conditioning), and even though Lavapies can be a loud bustling neighborhood, the building was silent at night. The elevator was really tiny but was able to fit my suitcases and always worked to get up to the 4th floor. There were cooking supplies, along with coffee, sugar, salt and olive oil so I was able to prepare meals at the apartment. The apartment is perfectly located as well, just 3 short blocks from the subway and a 24-hour grocery store, within walking distance to el Rastro (Sunday market) and the Reina Sofia museum, a 15 min walk from la Puerta del Sol, and near a lot of great bars and restaurants.
However, the best thing about my stay was definitely the host, Laura. When I arrived, Laura was so kind, took extra care to show me around her well-cared for apartment, and responded immediately to any inquiry that I had, checking in to make sure things were going well. I even had an issue with the bed being super uncomfortable, and that same day Laura brought in a brand new mattress (so now if you stay there, there's a super comfortable new mattress!) I have never had an experience with an Airbnb host that was so wonderful and had such a high level of hospitality, and I can't recommend enough that you book her apartment now! Gracias Laura!
