I had a very bad experience with the Waltham ESD, let me tell you the good news first.
The rooms are very nice, with comfortable beds, relatively new appliances and meticulous housekeeping.
The downsides are: office building construction right next door, their high-speed wireless was abyssmally slow(dial-up speeds), their air conditioners make a loud metallic snap evertime the compressor kicks on and the breakfast they offer consists of plain lenders bagels and horrible coffee.
An office bulding is being built right across the street, literally 200 ft away. Every morning at 6 AM, including saturday, I was awoken by dump trucks backing up, dumping loads and making a complete racket.(sounded like alarm clocks beeping and then small detonations as the lid on the dump body would slam open and shut).
The wifi is a known issue that they have been experiencing with their provider for weeks, I was counting on being able to do some online training videos, that never happened. Most nights I was lucky to even get onto MSN.
I checked out 2 other rooms after 3 sleepless nights, all of their air conditioners make that horrible snap sound, if you dont sleep like the dead, this will without a doubt affect your sleep.
Management was very understanding, and while they agreed to comp me for 2 nights, they raised the rates for the other nights by 45% to make up for it.
So there you have it, my 6-day experience at ESD of Waltham.
