Carlos went beyond the call of duty and waited until 2am to let us in after our flight was delayed. The flat is very convenient to Lisbon Central and all transport. It is basic but clean and fully equipped with what you may need. A taxi from the airport costs €10, and are available at the station 30m away. The windows are double glazed and have black out so you can lie in peacefully if needed. Carlos is very accessible and accommodating.
