Love this place. The view from the balcony is amazing and Ernest is a great host. The entire apartment feels fresh, welcoming and spacious.
Be sure to hang out in Graca and Alfama. There are some great places like Graça 77 and Maria Limao that are easily missed.
There's no elevator, so be prepared to walk a lot of stairs. But then again, Lisboa is made up of steep hills and small sidewalks. If you're going here you should be prepared for that.
