After traveling by car around several destinations between Porto and Lisbon, I want to drop off my car and spend one night in a hotel near the Lisbon airport before flying home on an 11:40 a.m. flight the next day. Is there a hotel you would recommend for that final night?

I always stay at the Tivoli hotel at Oriente station the night before an early flight out of Lisbon.

You can spend your last hours walking by the bay and having a nice dinner somewhere. There is also a massive supermarket in a mall across the street where I pick up stuff like peri peri sauce before heading out.

There are a couple of other hotels in the area. It is less than 10 minutes drive to the airport. There is a metro between the airport and Oriente station but cabs are cheap so I have never taken it.

Melia hotel Lisbon airport , it's within walking distance of the airport but they have a shuttle if you prefer.
