Pros +
- Location
- Valet parking on a frigid night!
- Nice new , good location
Cons -
- The fold out bed came without bedding which we had to request. There was a $25 fee for food that we were not notified of until checkout, and our showers in the morning were lukewarm at best.
- Did not care for the parking.
- Room was poorly lit, the bathroom door was glass with no sound proofing for privacy, and one mattress was old with spots that were sunk in. Three times in one night (about 11pm, 2am and 4am) a very loud train horn blasted 15 seconds multiple times.

The hotel was clean and well staffed with very helpful and courteous staff. It looked nice, plenty of on street parking, close to everything, and the Roof Top restaurant food was very good.
