Super obrigada, Tiago e Susana! This is great, convenient place to stay - super centrally located, with many amenities within walking distance (including the wonderful restaurant, Estrela da Bica, next door). In particular, this is a great set up for working remotely as there are two separate spaces/tables from which to work - a friend and I comfortably worked the entire week, including on regular video calls. The kitchen was well-equipped, and beds were comfortable and showers were hot and strong. I would bring ear plugs as there is some street noise at night.
Note that Lisbon, and especially this central area, is hilly and has a lot of steps in general. This apartment would be challenging if you were trying to avoid steps.
