The apartment is in a great location! There are lots of sightseeing options within walking distance, as well as a plethora of places to eat.
The only down sides were the noisy neighbors (typical when in a busy city and older building without soundproofing) and the hot water runs out quite quickly. If there is more than 1 of you, you will need to space your showers out far enough to allow the tank to heat up again.
If you are traveling alone, the mattress on the bottom bunk is much softer than the top bunk.
All in all, I enjoyed my stay in Lisbon. Angela is a good hostess and the apartment is adorable.
*Note - There is a washing machine, but no dryer. There is a clothes line outside the window, but obviously that can only be used in good weather.
