Great stay for those spending a few days in Lisbon - we spent 3 nights here.
It is a small place but if you plan to be out most of the day sightseeing, then it does the trick.
Be warned that the washroom (more specifically the shower) is very very tiny, so keep that in mind before booking. Just makes the shower a little annoying but not impossible. Another thing to note is that there was some noise from people walking upstairs so if you are a light sleeper maybe bring earplugs, but otherwise no distruptive noise from the street at night.
Lastly, seamless check in/communication and Julia was very friendly.
