Amazing location! Very central, right off a main square, perfect for exploring Lisbon.
The room is very big and comfortable. It's a shared apartment with some other bedrooms but this room includes access to it's own private bathroom (small) right across the hall with your own key. There is a shared kitchen and living room as well.
This is a very lively area and nightlife but the balcony doors/windows are pretty solid and block out most of the noise, unless you're super sensitive.
I would definitely stay here again.
