The Marine Hotel
Love it here, been many times, approx 10! Unit is old and tired and corridors can be split level which can be difficult but there's always help.... Room is great, one of my personal favourites, been in it before... There is a process of building improvement in place and being acted on which is great ...

Celtic Royal Hotel & Spa
Breakfast options were limited. Wifi was very poor, not strong enough to work on a laptop. Room was basic but did the job for one night. Clean throughout and staff were very friendly.
