I travel often - everywhere in fact. Every time I have a flight or stay over in Portland, I always look to book the Aloft first, and for the following reasons...
It's the perfect location. So many restaurants within walking distance - literally just across the street. The Max train has 2 stops nearby, one less than a block away. The max takes you to the airport, or downtown. You don't need a car at all.
Speaking of cars - this hotel does not charge for parking, and it has a 24 hour courtesy shuttle that picks you up/drops you off at the airport.
As for the hotel, the rooms are always clean and ready for your arrival. If you can, get a room on the North side of the hotel - you'll have a great view of the mountains, as well as a view of the runway without any noise.
The lobby and bar area are the big draw. The bar is always lively with the friendliest bartenders who know how to pour a good drink, and they are always entertaining. It's a great place to start or end your night. But truth be told, just get drinks - the food isn't anything to write home about, especially since there are so many restaurants close.
It has a lovely indoor pool which is clearly cared for, and it is also dog friendly.
All in all, it's a wonderful place, and it hires employees who truly care about the customer experience. Don't miss it!
