Joãos appartment was very close to the airport with an uber only costing €6. The appartment was spotlessly clean and very close to a supermarket, pubs and restaurants. There was also a metro round the corner in order to get to the centre quickly. However it was a 30 minute walk which we enjoyed aswell. João always responded quickly to any questions and sent me an excellent guide of things to do in Lisbon. I would highly recommend staying here.
