This apartment is absolutely magical! The view from the balcony (and the rest of the apartment for that matter) is so beautiful it negates the need to seek out bars with views in Lisbon because you've got it all right in the apartment! The space is a lot larger than it looks and it just feels really wonderful and homey. Also the apartment's kitchen is so well stocked that it felt like I was in someone's already functional home; not a rental apartment.
The location is also really great but be aware that it is on a hill and you essentially need to go up from all directions (plus 3 stories of stairs in the apartment) to get to it! (How else do you think you get such great views?!)
