Hotel Lobby bars and restaurant were lovely, reception staff on check in were efficient but not too friendly, on checking out were really nice.
Pool was lovely, on the small side but spotlessly clean, changing rooms great, no jacuzzi and the steam room was out of order but sauna was nice. Only complaint about the pool was you had to go the first floor then down stairs then up more stairs to get to it, despite there being a door through from the bar which it said was a fire exit.
Our main complaint was that the room was very small. We requested 2 double beds, however we got a room with a king size bed, which was a lot smaller than we have encountered in other marriotts. Also the tile grout in the bathroom was getting mouldy - could be doing with some attention. However we only stayed one night for a concert and did not complain.
The only way I would stay again is if we were guaranteed a larger room - The crowne plaza is being refurbished and looks lovely so perhaps this is a better option on a trip to glasgow
