My partner and I stayed here during our first trip to Lisbon and we thought the location was perfect! It was very close to the Cathedral and the Castelo de S. Jorge, and there are lots of little shops and restaurants close by.
We stayed in mid-September, and the apartment had an air conditioner, which came in handy.
Joana and Miguel are great hosts. Joana was there when we arrived to show us the space and answer our questions about things to do in Lisbon, and was accessible during our stay if we had questions about the apartment.
