This was a lovely, decent-sized apartment which is very well-maintained and in a good location. It's about fifteen minutes to walk to Aula Magna, which was where the event I was attending was held, and there's a bus about a two-minute walk away to bring you to San Sebastiao and the metro. From there it's easy to get to anywhere in Lisbon. Buy a Via Viagem card for bus and metro travel and you're sorted. It's also close to the airport, and there's at least one decent restaurant literally around the corner. Shannon, our host, was very helpful and informative. The apartment was clean and well appointed with washing machine, dishwasher, and fridge freezer, ideal for two couples or a family of four.
I would definitely hope to stay here again the next time I get to Lisbon, and I don't think there's higher praise than that!
