I recently stayed here for a couple nights with my husband and we loved the hotel - the lobby has a historic and elegant feel with a great scent circulating! The rooms feel very boutique with dark colored walls, and a very modern-vintage vibe. There are no mini-fridges in the standard room which is a bit strange for the class of the hotel. The front desk was very friendly, however it seemed they were still trying to get some things figured out.
The one big downside was the insanely loud bar/club right next to the lobby (it is part of the hotel and completely open to the lobby). If you are expecting to come back to a quiet and peaceful lobby to perhaps enjoy a cocktail or glass of wine and read a book (which my husband and I love doing in lobbies), you will be disappointed. On a friday and saturday night, it is extremely loud. We thought we'd be okay in our room, but we could still hear the faint sound of music and bass. This is definitely an issue for hotel guests and something Sentinel will have to figure out. It didn't dampen our stay that much, and I'd stay again, but I would for sure ask for a room higher up and on the opposite end of the hotel to avoid the noise. At one point I called down to the desk and asked when the music would stop and they just said "2am" without any apologies. A way to compensate for this would be perhaps to offer guests free drinks or something at the bar.
Regardless of the loud club next door, it is a great hotel, and we were able to walk everywhere. It is also across the street from some amazing street food. One tip - skip the $36 valet fee and park in the city/church garage a couple blocks away (the hotel will tell you where it is at). We ended up paying $10 a day to park there.
