We have just been on a family trip to Lisbon and Stayed at the Wonderful Nest.
The communication from the beginning was excellent. lots of suggestions of places to go and visit. Pedro was there to welcome us to the flat too. Extremely helpful.
The flat itself is up 3 flights of stairs but well worth the climb. The location is excellent, with the number 28 tram stop just down the road.
The Nest was very comfortable, with everything you would need. Good WiFi for the kids too!!
Would highly recommend this place.
