We really enjoyed our stay in Lisbon. Many things were within walking distance, or an easy bus ride. Barbara was very helpful and friendly, and gave us some great suggestions of things to do.
We should point out to people who will be visiting during rainy weather, the apartment can get cold, so you will need to request a heater. There isn't one in the apartment itself.
Other than that, we had a wonderful stay, and Barbara was a fantastic host!
