WARNING: You may not be able to check in to this hotel, despite having a reservation.
First, know this is the kind of hotel where people live. Several very low-income people and families are clearly living in this hotel, which is fine, but know this before booking. There's a reason this place is so cheap.
But worse, the front desk is often unattended. I booked this hotel through Orbitz and when I showed up (~8pm on a Friday), nobody was at the front desk and there was a sign to call a number. Nobody answered that number, nor the main number for the hotel. After hanging around outside the hotel and calling several times, I eventually bailed and booked another hotel. This could happen to you also.
Thankfully, Orbitz refunded me for this debacle, but don't expect the Tree Inn to actually be open when you arrive. In other words, just don't stay here.
