We stayed in 3 places while in Lisbon, and this was by far our favorite. The actual airbnb itself is fairly standard- the bed was comfy, the shower got cold pretty quick so make sure to get in & get out, and the noise level was low.
The main reason I would recommend this place is 1) the location, and 2) the host. The location is right in the heart of historical downtown Lisbon, and you are super close to authentic restaurants, historical monuments, transport, and really anything you would want to see while in Lisbon.
The host met us and provided some excellent recommendations on where to go and what to see. Lisbon is pretty large, so seeing a map & having someone local provide suggestions was very helpful.
I highly recommend staying here!
