Good location near grocery stores and restaurants. Hotel looks good from the outside but is dated inside the rooms. Breakfast is not included with all rooms. That means the food does not turn over as much as it would if all guests are invited, which I skipped because I like fresh breakfast.

Excellent Staff. Excellent Bed. Dreadful Shower - only way to get even luke warm water, was to have it almost in off position with just a trickle of water. Open the faucet any more and water was freezing. Even then, water pressure was miserable.
