We stayed for 9 nights at the Embassy Suites at Vanderbilt. The location was great, right in the heart of mid-town with plenty of bars nearby, we liked Oodies and the Stillery. With some good food options like Velvet Taco for a quick bite, or there was a great Ramen place across the road.
The shuttle bus was great - remember to tip your driver! Although the walk to downtown is fine during the day (aprox 20 mins), it wouldn't feel very safe at night. Although you can walk via the Gulch too.
The breakfast didn't provide many good vegetarian options (bacon + sausage mostly), so we didn't eat there every day.
The rooms were a great size, having the living area space for a longer stay meant some days we could still in the room more comfortably.
We went to the cocktail hour a few times, that was okay, but often we had plans which meant we missed the time.
Would recommend anyone to this hotel, great value for money for the location and facilities.
