Pros: Convenient downtown Miami location and relatively close to Miami International airport (about 20 minutes). It is a good place to stay for business and the staff was friendly and helpful enough. Spacious and well-maintained and clean room (the one I stayed in had a lovely city view).
Cons: Slow check-in. I waited for 20-30 minutes and the line was not even that long. I stayed at this hotel for a conference and the organizers had blocked rooms for attendees but when I checked-in the room wasn't ready. This is unacceptable especially since the hotel had already asked beforehand for a non-refundable deposit equivalent to a night's stay. If a hotel is expecting a significant number of guests to arrive, then they should be prepared for that. For a "luxury" hotel that is on the pricey side and caters to mostly a business clientele, charging $15 a day for internet usage (unless you are a Hilton Honors member) makes it seem that it is squeezing every cent out of guests. I have been to small B&Bs in far-flung places that offered internet connectivity free of charge.
I would not rule this hotel out for a few nights stay but would also recommend to check other options. It is a good 30-40 minutes drive from this hotel to South Beach (about a $35-45 cab ride depending on traffic) so if your purpose in Miami is to be close to the beach, this is not the most convenient location.
