Lovely hotel. All amenities were given and room was very clean. Walls are a little thin so you can hear your fellow guests nearby and above you. Only caveat was that the fridge was not working but overall it was a great place to stay! Front desk was very helpful and always had a smile and greeted when we were in the lobby.
