As city dwellers, we didn’t have an issue with noise as we’re used to noise. We had 2 couples and 2 teenagers (on the sofa bed) and it was a tight fit, but it worked quite well, since we mostly used the condo for sleeping. Good communication and various shower schedules (1/2 night, 1/2 morning) made it very workable.
There is only 1 key so if you’re traveling with someone else and might want to go your own ways occasionally, you’ll need to work out key arrangements with each other. Cell phones almost make this a non-issue.
We would definitely stay here again.
