We enjoyed this apartment, it's spacious and clean and has all you need. Diogo was helpful and always available, not that we needed him.
The best part was the location--it's on the perimeter of the hubbub, but the train and metro station are right there and you can be wherever you like in Lisbon within minutes. Up around the corner, the flea market is humming on Tuesdays and especially Saturdays, where it's a real scene and will draw you right up into the heart of the Alfama. It's walking distance to the Museo Azulejos, and there are a number of very nice restaurants in the neighborhood, convenient after a day of touring, and most of your fellow diners will be locals. Everyone is warm and friendly. Lisbon is wonderful and staying here was the perfect introduction for us.
