The location is super, very near to bars, supermarkets, train station, city centre, metro.
In the ad there's no mention that the toilet is outside the room and not even very near: this was very disappointed to discover after the booking. The toilets can't be closed with the key from outside, their doors are one near to the other, which make it possible to use the incorrect one by mistake, which was exactly what happened in our case, where our bathroom was used by another couple. Obviously this is not a owner's fault, but still something easily avoidable with making the keys work.
Overall, considering the high price of the apartments in lisbona, it's a good value place.
