Perhaps for people who are used to it, it may not be as big of a deal but we were not expecting the neighborhood to be what it was. The amount of homeless people staying in the surrounding streets was overwhelming and we were followed, yelled at, and panhandled every time we walked out the door. The loft is really lovely and comfortable, but we seriously were not prepared to be followed and called at every time we walked out the door for several blocks. Most of our interactions were harmless, but once or twice we felt unsafe enough that it made us uncomfortable to return to the property after dark (though in fairness we returned after dark every night and nothing ever happened). It's a shame because Pioneer Square seems like a cool neighborhood, but we found ourselves wanting to stay away as much as possible except to sleep. Just our two cents.
As far as the property goes, the loft is very beautiful and well-apportioned. There was a hand-written card and snacks, as well as a comfortable king-size bed and a small but more than sufficient kitchen (we didn't cook though so can't speak to functionality). There was construction right outside the windows, but we only noticed the noise a couple times and it wasn't super distracting. It is an old building so you do hear people walking around, but everyone was considerate and nothing was too loud (other than one night we heard people screaming at each other outside- but it was brief).
Overall the property was lovely but the neighborhood wasn't the right fit for us. Someone more used to vibrant city life would love it here though. :)
