We live in Porto and visit Lisbon occasionally for family weekend trips, or work trips. This time it was a family trip (with a 2-year-old) and Alexandra was a great host from booking until we left the apartment. She's always responsive, but most of the time also proactive, sharing detailed check-in information and other useful tips before even you reach Lisbon.
Apartment is in a very quiet neighborhood, and it looks brand new. It's decorated with a great taste, and both the living room and the bedroom is very comfortable, and enough space for a family of 3. There is a nice, clean kitchen with everything you need for cooking. And a large, nice bathroom with a large shower.
We are super happy with our stay, and I recommend Alexandra's place for anyone visiting Lisbon.
