Alfonso was sooo friendly and helpful! The apartment was beautiful and was located in a great area. It did feel a bit sketchy early in the morning when we arrived, but anyone who's used to living in a big city anywhere in the world would feel comfortable there. It's just like anywhere else. Be aware of your surroundings and act like you know what you're doing. The apartment itself was adorable and the perfect size for two people. The futon bed was a bit uncomfortable, but I'm also very picky with mattresses. The kitchen and bathrooms were both SO nice, especially for Europe. My friend who lives in Madrid and is American said he would KILL to have this as his apartment in Madrid. The most important thing is that Alfonso was incredibly friendly, flexible and welcoming. He also let me communicate with him using WhatsApp and was extremely responsive. He made us feel welcome and at home in a city I've never been in before. Overall, it was great, and I would recommend it to anyone who wants a nice apartment at an excellent price, while in Madrid.
