Most annoying: the locks on the rooms seem to reset constantly (sometimes multiple times a day) so you have to queue up to get new keys daily. You see a lot of annoyance/anger in the lines daily. Even on a holiday weekend they didn't bring in more staff to handle the volume. Single biggest issue: the lines at the front desk are always ridiculously long (they really need a separate queue for just rekeying). Random bonus: the Carnaval Grand Parade goes right in front of the hotel so the parade view is great!
It is walkable to a lot of shopping and restaurants (goto Que Pasa, Gauchos Argentina, Casa Tua and the Dutch Pancakehouse for breakfast or schnitzel for dinner!!)
Lots of flamingos and iguanas and beautiful views.
