Great stay! Walking distance to downtown. We didn’t get to check out the rooftop bar but lounge was nice and breakfast was pleasant! Overall stay was great.

Pros (+) This hotel is really excellent; new, clean, friendly staff and a great location. However, things we prize when staying at a hotel is getting a good night sleep and the walls of this hotel are paper thin. So thin, that we could hear our next door neighbors phone on vibrate mode not to mention him bellowing into his phone at 6:15 in the morning.
Cons (-) Sound proof walls; something you would think is one of the first things that would be designed into a hotel.
