The flat is exactly as described. The location is amazing - everything is walkable. The trams, trains and buses are very close so if your struggling to walk to can hop on those easily.
There was minimal - no noise from the building next door and none at all on the weekends so I wouldn’t let this put you off. The building and flat are all very new and clean, there is also the added bonus of having a lift.
The main road below is a little busy at night but every street in central Lisbon is the same.
Overall we had a great stay with no issues.
