Frederico's place is located in the center of the city and it is very convenient to everything and you can walk to anywhere you would like to go to including some of the night life spots. I met Joana, Frederico's wife and she was very sweet and very accommodating. We didn't have a specific time to check in since we were traveling all over Portugal and Joana accommodated our check in time. The apartment is comfy and clean and sleeps 4. The only minor negative is that my boyfriend is 6'1 and the bathroom is small which means the shower is small and he couldn't fit lol. (He's a big guy) But if your a tall person and if your staying there for only 2 -3 nights then it's no big deal you can manage. The apartment is on the 5th floor and there is no elevator. But most apartments in Portugal that are older don't usually have elevators. I would recommend this apartment to anyone going to visit Lisbon. Location, location, location !
