Brutal...could NOT even get inside the Building (had to wait for a pre-existing guest to return to the premises [with his take away lunch] and open the Front door for himself to gain entrance), after ringing the doorbell and knocking on the Front door for over 45 minutes!! NO staff members on the premises at all and there was NO "front desk" to check in at, even though the property states there is in the 'Confirmation' email that I received. My Guest and I were out a Room, I ended up booking in at another Hotel and he ended up driving back home to the very south of Ireland in Wexford! Absolutely NO/Zero compensation whatsoever (not even partial compensation)!! I would NOT even consider staying there ever again...NOT even if it was FREE!! Front door is a single man door which is NOT very well marked either, so very hard to spot unless you have your Google Maps handy! GOOD Luck if you decide to stay there!!! The Positive is it is handy to the core of the Dublin City and the Train....but there is a fairly steep hill (upwards) for 2 blocks to reach the Building. ***Plenty of well marked Hotels (down the hill and at more level ground), closer to the core of Dublin City, closer to the Trains, and closer to the River, than KGT House...where they actually have a 'Front Desk' with staff members onsite!!
