We arrived very late and Vitor came to check us in after midnight, which was awesome from him. He is a great guy and can give you very helpful tipps.
The taxi to the airport costs around 13-15 EUR. The private transport Vitor arranged for us was super nice, too (price 30 EUR)
The appartment is very comfortable with plenty of space and we absolutely loved it (my wife, our baby girl and I). It is located on a legendary street in the middle of the great night life of Lisbon - wide variety of bars, cafes and restaurants less than 2 min away! The supermarket and the tram station (tram 28 - the sighseeing line) are just 1 min away.
One only needs to open the windows to feel inside the party. With the windows closed it is quiet. The house is very old, but recently renovated and with modern and comfortable furniture. This makes it charming, but the inner walls are a bit thin and one can hear the neighbours, which was not a big problem for us. I definitely recomend this place.
