Retro vibe, very cool touches in room
Stayed one night at the Doubletree while attending a show at Scullers Jazz Club... our room was upgraded to a bi-level suite on the top floor (HHonors Gold member) - awesome two story room with a full living room, fantastic view of the river and a king bed in the loft area. 
The shower had 5 shower heads - 1 traditional, 1 handheld and 3 that came out of the wall and could be angled - awesome! In addition the mirror in the bathroom had a tv built in behind the glass - something I had never seen in a hotel before. Very cool feature !
Breakfast buffet was decent, typical for a Hilton property. Parking was in the attached lot and $35.00 for the night.
The onlly downside was that we weren't there long enough to fully enjoy the room or the other amenities at the hotel. Definitely would return and highly recommend it if you are attending a show or in the local area.
