I have my own private space in the dead middle of Baltimore. No, I am not located in the BWI area or the Inner Harbor. Take your finger & put it on a map, hitting the exact middle of the city & you are resting on my boudoir. The great thing about the area is that is plenty of free street parking, in a great & safe neighborhood.
The bad part is that I do not live there, nor do I hang out in the neighborhood, waiting for you to schedule a visit. (Remember, I do this as a hobby) So, your best bet is to schedule your visit at least a day in advance. You can try & request a same day visit. Perhaps it may even work out.
