DON'T DO IT! I just stayed there last March, and it was a really horrible place to stay. It honestly takes a lot for me to say that about a hotel...I'm not a fancy girl, or even a three star hotel girl! Give me your everyday Holiday Inn and I'm in heaven!
I first stayed at Days Suites Maingate (by Oldtown, correct?) several years ago...I'm guessing 1997 or 1998. I was rather young (12-14 years old) and I remember it being fine. Tons of space, a little dated, but fine.
March, however, was a different story. We booked it because it was the cheapest thing we could get for that much space. The room was not very clean, and all the bedding was SO OLD! It seemed like every comforter and sheet had a hole or stain on it...yuck. I felt really yucky going to sleep in that bed every night...and that's not a good feeling to have on vacation. Also, while this might be a unique situation, there were many unruly guests there (we called them the loud angry cubans!) who hung arround the corridors yelling and screaming at all hours of the night. My boyfriend slept in the living room (right off main door) and he said it was quite frightening.
After our stay, we all agreed that it would have been better just to stay at a "regular" hotel room that at least would have been clean and a little quieter. We are going in January and are staying at Buena Vista Suites for $89 a night.
If your options are staying at the Days Suites for that price, or not going at all, I would say go and just bear it (we survived!). But...if you are at all flexible in your price (or really don't need 3 beds) I would look elsewhere.
Good Luck (and sorry to be the bearer of bad news!)
