The hotel was good, close to airport and acceptable. I tried to get a shuttle to pick me up but they never responded. $17 taxi ride there. The breakfast is served on paper plates and plastic spoons and forks. It is a good one nighter between flights, what I used it for on a missed connection.

Lobby looked outdated but staff was nice and room was okay. One thing I did not like is the pillows. They’re very very soft and they sink in. I used 4 pillows in order to have a firmness of a normal one. Overall, average stay. Some pillow cases had stains on them.
