The flat is very cool I really loved the wooden ceiling, the split kitchen, the bed and the AirCo.
There are two details for you to consider:
i) Although the location is central, you have to do some walking to access public transportation like the metro since the flat is based like below a highway. If you do Uber then is fine.
ii) This particular location is on the route of the planes arriving to Lisbon Airport so it can be quite noisy.
