What an absolute gem of a hotel. Location is excellent for the center of Dublin, right beside the Ha'penny Bridge. Check in was fast, friendly and efficient. Our room was modern, spacious with a great little kitchen area with all the basics you would need for a few days. Would 100% reccommend!

The location of the hotel was very central, very close to the main Temple Bar area. Walking distance to everywhere we wanted to go. We travelled by car and made use of nearby car parking that the hotel had a partnership with. However finding the hotel by car was difficult and we had to ring the hotel twice for help. Internally the hotel was beautiful with a lovely lobby area to sit for a drink and a breakfast area which was very modern and clean. Our bedroom was basic with a very small double bed and noisy. We could hear every single person who walked past in the corridor and hear other doors closing all night.
