Colonnade Hotel: A list of pros and cons
Pros: 
1. Very nice staff - very helpful and polite. The guy at the front desk helped me figure out a run around the Charles.
2. Great location - right next to the conference center and a high-end shopping center, restaurants, in a very good part of town. 
3. Comfortable bed and pillows. 
4. Good water pressure in the shower. 
5. Pretty thick walls. 
6. Internet (once purchased) was fast and reliable for the time I was there. 
Cons: 
1. Biggest con if you're at all sensitive to noise when you sleep ---> Very loud A/C in rooms. I thought someone was vacuuming directly outside my room when it kicked in. I asked about it at the front desk and the guy told me that all rooms had the same loud A/C. I tried sleeping with earplugs but it kept waking me up every time it kicked on, so I ended up sleeping without A/C and waking up in a ~80+ degree room. Made it difficult to get a decent night's sleep. 
2. Internet is $14/day. Other miscellaneous add on charges to be aware of. 
3. Fan in the bathroom was broken. Bedside light was broken.
