yes, there are air conditioning in all our hotel AMBERTON Cozy rooms.
It is very good, it will freeze you out if you set it to low.
We just stayed and the a.c.was either broken or just awful. First room was so very hot that we were miserable. Thought it was just that room, but second room was also pretty bad. Lobby and halls are very cool. We literally kept our door open until we were ready to fall asleep.
