I'll start out with that I'm a very light sleeper...so based on a few previous reviews, where street noise in the evening was mentioned, I was slightly concerned about how much sleep I was likely to get during our stay - especially since we were staying over a weekend. However, all the positive comments regarding the loft's location, cleanliness, etc. trumped our reservation and we booked the loft.
We are extremely pleased that we did. All the positive reviews are dead on, and I won't waste your time repeating them. The loft was awesome.
So how was the noise? What noise?? We turned on the fan in the bedroom and slept like babies. I didn't wake up once in. the two nights we stayed at the loft. That rarely happens when we stay at conventional hotel.
So, if street noise is your only concern about booking this place, put your fear to rest, and just do it!
