The location is un-beatable. There's a ton of cute cafes and restaurants within 5-min walking distance. Not to mention there's a cute bakery (Ceres Boulangerie) just around the corner. The apartment is good size with 3 bedrooms and two bathrooms.
It's also on the tram 28 route, so you can see the tram from your balcony window. It's super cute and pretty much the exact experience you'd want coming to Lisbon.
One thing to note is that it might be a bit noisy considering it's so close to the tram track. Other than that, this is a perfect airbnb you'd want to stay at if you are coming to Lisbon.
