I've never been inside or stayed there, so I can't give you a review of the hotel and its amenities. But, as a local, I can address to the location of where the hotel is. Although it's called The Old Town Inn, it's not really in what is considered "Old Town." It's on the outskirts of the Old Town tourist area, which is on the East Side of the freeway.
Pacific Highway, which is where the hotel is located, is more of what I consider an "industrial area" with businesses and wherehouses and the highway runs right next to and under Interstate 5 (a very, very busy freeway).
Yes, it's close to the The Old Town Trolley Transit Center. The OT Trolley Transit Center is a main hub for a lot of people who carpool to downtown (I've parked there and taken the trolley when I had to report for jury duty), so you'll be near parking lots filled with cars.
I'm afraid that you might be a bit disappointed with the ambiance of the surrounding area of the hotel, but if that doesn't bother you, then consider it. I think there are nicer places to stay in San Diego with all the same amenities and conveniences that The Old Town Inn has to offer without breaking the bank. But that's JMHO.
If you still want to stay in Old Town, here are some to consider:

Also, Hotel Circle in Mission Valley is close to Old Town and it has a lot of hotels in the area that I'm sure are reasonably priced:

Hope this helps.
