Below usual Residence Inn standards.
Biggest issue was noise, both from the surrounding area and from within the hotel itself. Gaines Street is loud at all hours of the night from cars with custom exhaust racing out of the traffic signals, and from drunk students.
Inside, the lobby music is pumping. It pervades the first floor guest rooms and the business center. One night, two staff were standing outside my door talking loudly at 2:15 AM for about 20 minutes. Woke me up. Could have easily had that conversation 50 feet away in the lobby.
Front desk staff were minimally, and grudgingly, helpful. For the first time in my life, after 25 years in a travel-heavy job, I actually asked to switch rooms because the first night was so bad. It took a few minutes of politely cajoling the unhelpful person at the desk before a manager overheard, took pity, and arranged for a different room. New room was much better, but still not great.
Room quality was so-so. Bed and pillows were lumpy, sheets and towels were worn through in spots, couch upholstery and rug were stained all over, etc. It was clean enough, but not what I expect from Residence Inn.
Room was spacious with nice layout for eating/working/sleeping/relaxing. You can't beat Residence Inn in this respect.
If you want to party and be able to stumble home easily, this hotel would be a good choice. If you need to work and get some sleep, stay up on capitol hill.
