This place is probably not the best hotel in town but at 60 bucks including tax is a great value. They have a full breakfast in their restraunt and a friendly staff. There is a lounge downstairs after 4pm if you want a drink or want to play pool. I'll be staying there again because it was clean and comfortable.

Looking for a mini vacation before heading up to Yellowstone we chose to stay at the Guesthouse. Kassie treated us kind and gave us a nice room at an inexpensive rate. In the morning I was expecting the typical " free hot breakfast " and was pleasantly surprised to find a friendly server and the spread of eggs, sausage, pancakes and hashbrowns! My only disatisfaction was the ice machine was broken and had to go to the from desk for ice.

After extensive planning with Kassie from the Guesthouse Inn, (we live in Idaho Falls) we felt our 4th of July was perfect for the anticipation of our family coming from Ohio to experience Idaho Falls's famous day of celebration with an evening of fireworks which is staged next to the hotel. Kassie went out of her way to make sure our group would enjoy the afternoon & evening and the use of the room we had reserved. Unfortunately, we had to cancel our reservation on July 3rd due to a death in the family. Kassie refunded our money which we used for the funeral expenses. Thank you for being so understanding.

So under pressure from the family we stopped in Idaho Falls and I reluctantly agreed to find accommodations in Idaho Falls. Initially I was attracted to Guesthouse Inn from the massive billboard on I-15 promising rooms for $59 and a free breakfast. Turns out the cost was $75 and the breakfast was only so-so.
The hotel in itself is somewhere between well kept and tired looking, the check in staff were friendly but ask them about a good pizza joint nearby and they'll tell you Domino's but of course that had nothing to do with the Domino's menus in the rooms or anything like that. Nope, no collusion there.
Still the room was decent enough, albeit plain, and it passed our mandatory bed bug check, however the hot tub downstairs was showing its age, and what we thought was a steam room was a janitors closet.
The next morning before leaving we stopped by for our free breakfast, don't forget to get the tickets from the front desk so you can eat BTW, and eat what was frankly a disappointing spread.
There was the usual hot and cold stuff but the pickings were slim, the bread and cereal was dry and the pancakes were only okay. Don't get me wrong , free breakfasts are great as they save me dishing out money later on, but the front desk staff made it out to be a cavalcade of great food that brings them in from miles around, but it was a case of overpromising and under delivering I'm afraid.
So a fail on the breakfast I'm afraid however, the restaurant staff were very nice and attentive.
In essence the Guesthouse Inn and Suites is a lot like Idaho Falls, fine for a stopover when you're tired but best to push on as soon as possible and caveat emptor on the breakfast.
