SpringHill Suites Phoenix Tempe/Airport is a good place if you like airplanes. The hotel is directly under the main approach for the busy Phoenix Sky Harbor Airport which makes it pretty convenient for travelers, although they are located in a business park area of Tempe requiring a bit of a journey to access restaurants and nightlife.
The airplanes are not super annoying since the hotel has a good amount of soundproofing, but you will hear them zoom by quite often. I did not hear them at night which made sleeping better. The overall hotel is the standard issue with a nice pool and breakfast area. The rooms are good with a nice memory foam mattress and good water pressure. I am not a fan of Marriot's couches and tables which seem to be hard and awkward.
This is a decent, but basic option in the area. The airplane noise was a bit too much for me, but I cannot find too much fault in the service and amenities in this price range. Free breakfast and shuttles are very nice and convenient, although its a bit weird to be in my gym shorts eating next to fully dressed business people heading off to conquer the world!
