Convenient Location, but Not the Best Doubletree
Booking was done on-line, but not through the Hilton site, since their site was not working for several days straight. 
Arrived and the Valet Parking was efficient. $37/day with minimal wait to get your car. Check-in was slightly less than stellar. We had three in our party, as I specified on my reservation, but we were given breakfast vouchers for two (I had paid for three when I booked). We were given two cookies (not that I NEEDED a cookie, it simply represented the LACK of attention to detail.)
The room was comfortable enough. I didn't find it to be all that small. It lacked the common find in most hotels, highlighting room service offerings, neighborhood restaurants, etc. The bathroom is small and while the tub and tile were clean, the walls were stained. 
Breakfast was fine. It was a basic hotel hot breakfast buffet, but is handy. It offered fresh omelets and fresh fruit in addition to scrambled eggs, bacon, sausage, etc. Our server was delightfully attentive.
At first glance, the dining room looks nice, but I did notice that even in the dining room, the walls were quite grimy. 
This hotel is located in a great neighborhood, with plenty of restaurants within a short walk. If you stay in Doubletree hotels, this hotel may not match up to your experiences elsewhere, but it is a safe, convenient location. My hope is that they start to pay attention to the details. It shows when they don't.
