The apartment is located perfectly to explore the city by foot and the metro/tram. Walk only uphill for 10 min and you will have a great view over Lisboa. The metro station and the tram are also super close. There are a lot of small shops around to buy your groceries.
The flat was much smaller than we expected from the pictures, however it was newly refurbished, nice and cosy. For three people it was good, but we couldn't imagine to stay with four. There is just little space to put the suitcases and your belongings.
It's a quiet neighborhood, however, currently there is a big construction site nearby where trucks also arrive in the middle of the night.
