Well I actually called to reserve a spot a few weeks ago. The lady that answered was rude and acted annoyed with me right off the bat. I asked if the rooms were still $40/night and she just said "no, $45".
Then I asked if they had any extra storage space (since we are basically moving) and she simply said "one box". I paused to figure out what that meant, and tried to clarify, "so, there's room to store one box?" And she said something to the effect of "No! one box of storage." Well we went around a few times, and I still wasn't clear what she was talking about, and she made no effort to explain. I could tell she wasn't interested in the conversation so I just politely said "thanks"
Next I called Walnut Gardens, and it was a completely different story. The lady was very friendly and talkative. The rooms were still the same price, ($32 for me) and apparently they actually own a small self storage building not far from the apartments and give you half off if you're staying there.
So, no citadel for me.
