We (family of 4 with children 12 & 10 yo) had an amazing experience with Mario's apartment. He always responded to messages right away while we were making plans to visit. It was exactly as pictured, very clean, and most importantly in the best location! Mario was great, arranged transportation from the airport, stored our luggage until apartment was ready, and let us check in early. He gave us great suggestions for restaurants in the area and had a little map of the immediate surroundings which was very helpful. He left us a nice bottle of wine too! Many of the more well known areas to sightsee are right within walking distance, even with all the hills of Lisbon. It's a fabulous and friendly city to explore!
