We had a great time exploring Lisbon with this apartment as a base. The location is definitely its strong suit, with the Baixa Chiado metro stop at the end of the street and the historic centre at walking distance.
Facilities were good. Wifi was strong enough for videocalls.
The fridge was a bit loud and around May 2021, there was still construction in the morning. Should not matter if you will wake up on time to explore the city.
We would recommend the place - it was great value!
