We enjoyed our stay in Lisbon, and this appartement is perfectly located to explore the city.
Its facilities and confort (bedding and bathroom) were a bit limited for the 6 of us, but we did not stay that long at home and preferred to go out (super nice roof top bar 50m away).
Communication is accurate and rigourous as you feel that Luis' team knows its business.
We would have prefer to get more information and deep tips regarding the immediate neighborhood (breakfast confeitarias, Portuguese cuisine restaurants...) - friendly moments was definitely too much asking - as we are Airbnb enthousiastics from the early times, but if you look for a confortable appartement to rent over your stay in Lisbon, it is very fair choice.
