The hotel lobby is beautiful!
We went to the rooftop for dinner and they didn’t have enough help.

9 / 10Outstanding·Aug 2026
Great location, new and clean facility. Also had a great rooftop bar/restaurant
Construction next door blocking most of the views but not much you can do about that
6 / 10Average·Jan 2026
Two people stood out: Manager was a really good guy and the English bar manager was excellent.
1) Very noisy AC unit made it hard to sleep. 2) The website clearly shows the rooms ahev views...but when you arrive a building has been erected next door. Misleading 3) Whilst the manager and bar manager were excellent some of the other staff appeared very grumpy and not willing to help. Strange
