Checked in 6/13 for one night. Nasty odor in the first room. Possibly a cleaning product as it had a strong ammonia smell, but also something else vaguely nauseating. Went down to the front desk, very courteous, promptly put us in another room. Unfortunately, turned out that room had a broken air conditioner! Wouldn’t run - 74 in room with thermostat set at 62. Called front desk (“Hey it’s us again…”) and they sent up a maintenance person who disconnected the unit from the wall thermostat so we could set it manually which was fine. But wow, was that darn thing loud! Ten feet from the bed, right? And cycled on and off all night with a sort of cough and rattle. Apple watch said I only for just under three and a half hours of sleep in the ten plus hrs I was in bed.
So, Pros: great location, very friendly, competent, responsive staff.
Cons: one room with strong ammonia (urine?) smell; next room with crappy a/c.
We won’t be going back. Plenty of other options in and around Portsmouth.
