I've been to numerous apartments in Lisbon. This one is literally the best one.
The location is 100/100. It is in the heart of Principe Real, where all the life is going around. At the same time, it is located in a quiet patio where (from where) you can easily arrive by car. The average Uber waiting time was 2-3 minutes :)
The apartment by itself is big, perfectly clean and fully equipped. We felt at home!
Another amazing thing is the host. Available and supportive all the time. At the end of our stay, we had an unpleasant situation with the flight cancellation. As a result, the host just let us stay a bit more than expected to make our way back home more convenient.
Perfect price-to-quality, I definitely recommend renting the place
