Wonderful hotel-like accommodation and prime location. I had a roughly two-week stay, but I would say particularly for a shorter stay, maybe for your first time in Lisbon, this is great (mainly because there’s 9 rooms and one kitchen, but many bathrooms as some rooms have ensuite). It’s refurbished, clean, private, quiet, and even the ground floor street-facing window is a little elevated which is a plus.
The manager/host really helped me out with some requests very promptly, like a new duvet cover and a small heater during a really cold period. The only part that wasn’t great was motion-sensing lights turning off constantly but it’s not too bad and helps the environment.
