Friendly and Helpful Staff and Beautiful Hotel
I travel to Dallas every month for work... just for 3 days but the frequency has given me a chance to try a variety of hotels. I've been staying at the Warwick Melrose for a while now for several reasons.
1) Friendly and helpful staff - Eric, Leon and others at the hotel are genuinely friendly and helpful. Aside from the obvious staff duties, everyone takes the time to know you. From friendly conversation to helpful tips for dinner, it is nice to feel like you're staying with friends.
2) Nice accommodations - Other than the fact that there is no lighting in the showers and they use opaque curtains, the room accommodations are nice. Plenty of pillows, plenty of room and always clean and comfortable.
3) Convenient location - This hotel is really convenient to most everything. For driving, you're just off I35, the Dallas North Tollway and I75. There are plenty of restaurants and bars in the area and even a Starbucks just a block away. Granted, the required valet parking costs are a bit steep considering that parking is generally easy to come by in Dallas (lived there until 2011). 
All in all, I would definitely recommend this hotel for all of the reasons above.
