We arrived late in Lisbon and were welcomed by Joana's friend for a late night check-in (with extra fee). Joana's apartment is spatious, very well equipped, nicely decorated with quality furniture. It comes with an underground parking space which is really a plus if you have rented a car. Bedding is really excellent and we slept very well (although we can hear a little bit of the street).
Even though we couldn't meet Joana during our stay, she has always been available and responsive to our needs (by SMS/email).
In the end, Joana's apartment is perfectly suited to accomodate a family for a short stay in Lisbon and we were very satisfied with our choice.
