Nice place for a great price. Paid a little extra for a bigger room as the regular rooms are pretty tiny, I guess that’s why they call it “Micro…” Place clean and staff friendly

No pool. Down for maintenance. Did not find out until we got to the facility & it was non refundable. Could not afford to NOT stay. We made the most of it. Booked a room at another facility the next night that had their pool open, beautiful rooms, great staff & half the price.
