To make it short: I can recommend this place for staying several days in Lisbon.
This place has AC, a well equipped kitchen, some basics so start with and comfy beds. Note that the double bed is in the living room and has no door to separate it.
We've been grateful to have the welcoming wine, cheese and bread the fridge.
The flat is very central and many nice places for coffee and food are just around the corner.
During our stay, there came noise from the air ventilation system of the restaurant downstairs. During their business hours, the engine for the fan was running and produced a very piercing sound. Fortunately, it was switched off over the night. We were talking to the host: it's a current issue and they are working on a solution.
Communication with Angélica was easy and responds came quickly.
