I stayed at 830 Park while attending a conference at the convention center. Patricia and Matt were super friendly and communicative, and even kept track of my luggage for me before check-in when I arrived! The place was clean, quiet (a little noise from the nearby train, but it did not bother me), and had all the amenities I needed to prepare food and freshen up. It's only a 15-20 minute walk from the convention center and the nearby grocery outlet was really convenient. The neighborhood seems fine to me - I am female, traveling alone, and never felt unsafe, even walking back from downtown at night. I had a great stay and would definitely recommend Matt and Patricia's place.
