Rita apartment is very nice. It is big, very well decorated. you can fill that this is a real home.
Localization: It is in walkable distance from Belem (15min), it is a little far from the downtown, but if you like to walk, it is possible (I think around 30/40 min).
It is close to the train station Alcantara-mar (to cascais) and Alcantara-terra (to Sintra) and the tranway 15 (to belem and downtown). But it is also close to the river Tagus (5min). On the river bank, you can rent some electric scooter for 0.15€ a minute. This is what i used to go to everywhere. These scooter are located in several places in the city and you can install the app to locate them.
The apartment: the bed is confortable, the lining smelling clean, kitchen well equipped, also with dishes washing machine, but no oven. It is located in a old building, but everything works well, and you can see that it was recent renovated.
Check-in/Check-on: you can do everything using your phone. With an app, you can open the doors, no keys needed.
Weak point: a bad smell coming from the sewer. The neighbor was doing renovation, so it was a little bit noisy during the day. Close to bars, so sometimes you car hear the music, but nothing to disturb your sleep if you are not a very light sleeper.
Apartment super recommended!!!!
