We stayed at Helen & Martín’s apartment for 28 nights. It is a perfect location for exploring Madrid on foot, just a short walk from Plaza Mayor. The space had everything we needed to feel at home for our long stay including a fully stocked kitchen, washing machine, and comfortable bed. The wifi was reliable and super fast (we got downloads of 390 mbps and uploads of 340 mbps). Helen & Martín are fantastic hosts and gave us lots of tips for exploring the city. They even met up with us one day for adult beverages! We had a great stay and 100% recommend.
