I am here at the Miami River Inn right now as I am writing this. Of course this is not the Taj Mahal - it is not intended to be. There is nothing wrong with it however ! It is just like so many other B&B type establishments that are often referred to as "quaint" - having "character" - "shabby chic" - etc etc.
If it were in Key West or Coconut Grove it would no doubt get constant praise.
Take it from someone who has traveled around the world MANY times. . . it is clean, comfortable, and a perfectly viable option. Old - yes. . . that is part of the appeal.
I hesitate to recommend it - but only because tend to want to save it for myself and my closest friends. . .
If you want a Front Desk that is manned 24 hours a day - then of course go to the Holiday Inn / or similar.
You have no recent hotel searches.
