I stayed in Alberto's place for six nights in mid-March. The description of the apartment is that it is a "prime location" but I didn't realize how perfect it was until we arrived. It is about a five minute walk from the Metro station and three minutes from Gran Via. I took the Metro a lot on my trip and walked a great deal every day and this location enabled both of those. Our close proximity to main streets and plazas meant that walking in a one kilometer radius we would find a lot of places to shop, eat and explore. The combination of location and affordability make this a fantastic place to stay in Madrid. Alberto as a host was very accommodating and answered all my messages very quickly and clearly. I would definitely recommend his location to other travelers.
