We stayed at this location on a recommendation from a friend and could not have been happier. It is in an awesome location, beautiful apartment and the communication with the hosts was wonderful. The distance from downtown Lisbon was a quick ride on the tram, which was less than a 2 minute walk from the front door. Truly, we could not have picked a better place to stay! Do remember to bring your own soap and shampoo (we stupidly forgot ours but a quick trip to the local market solved it). It is a walk-up but definitely worth it!!!
We used the car service for pick-up (35 euro) from the airport and it was a great decision. We did take the tram and metro back to the airport at the end of our trip and it was easy (and considerably cheaper for a family of 4).
