I stayed at Timberline during my 9 mo. stay in Flagstaff. Our family had a good experience. Office was good to deal with, maintenance was prompt and courtious. Walls/floors don't transmit much noise (never heard neighbors). Parking was not a problem (1 assigned, unassigned close by). Floor plan is great.
* They need a new (better) snow removal contractor. The dude leaves too much snow to drive through.
I have lived a number of places through my travels and I highly recommend this apartment complex.
