I had a great time at Joao's River House. He was there to welcome me and show me how to access the building and get in/out of the parking garage. There were multiple handmade tourist books with ideas for day trips and things to see in the city and surrounding area. The kitchen had all I needed to cook and condiments on hand for breakfasts.
The apartment is a bit of a walk from the main sights in the old part of Lisbon but is worth the stroll (or take a bus). Also the walls were not super soundproof so you could hear doors closing next door but nothing that kept me up.
With that said, if you are looking for a place outside of the old part of Lisbon with underground parking and easy access to the airport then this your place!
