My wife, 6-month old, and I had a wonderful experience.
First, we were met at the AirBnB by Bruno, who helps manage the unit, and spent over 45 minutes walking us through the apartment, complete with a full binder outlining where we should eat, explore, etc.
The unit (upon request) was also furnished with a pack and play, baby toys and a bath, which was extremely helpful, as we were traveling from the US, and eliminated several thing we would have had to otherwise pack.
Lastly, they provided transportation to and from the airport at a significantly cheaper rate than local cabs.
If this wasn't good enough, the unit is also in the heart of Alfama, and within a few minutes walk of several great food spots, look-out points, etc.
Courtesy Apartments provided exceptional service, and we would highly recommend staying with them!
Thank you again to Bruno and team for all your help!
