Anas Apartment is just perfect for a city trip. Perfectly located, beautifully designed and very very clean. It has everything you need for 4 People. Very cosy beds.
It's right in the middle, there are great restaurants (Maria Catitta!!) and Bars literally in the same building. You can also easily walk to most Lisbon sights. Despite that, it's still quiet in the night because the Apartment has very good windows.
Thanks again ana and paulina, it was wonderful!
