I’ve stayed in Lisbon many times and Alfama is a solid choice for a locale unlike traditional spots in other European capitals. This is no longer a traditional Portuguese neighborhood; roughly half of all dwellings have been converted to vacation rentals and the neighborhood’s character has been destroyed. You’ll encounter drunken university students who are loud at times and your neighbors will also be tourists.
With that said, if Alfama still appeals to you then you can do no better than this apartment.
Andreia has created a stylish, comfortable, ultra clean apartment with very convenience of home. This is someplace I would happily stay in again. Being able to wash laundry while away was a big plus! And the setup is perfect for dual couples as the bedrooms are on opposite ends of the home.
The neighborhood noise level is low — no barking area dogs, no traffic sounds. There are many minimarkets within a 30 second walk of the door and all of Alfama’s Moorish attractions are within 10 mins. If the 28 tramcar appeals then it’s also just outside the door.
