Rumi's place was very conveniently located with lots of great shops and restaurants within walking distance in Little Tokyo. There's no on-site parking, but there's a public lot just one block away (Joe's Auto Park, across from Suehiro Cafe) which is really cheap ($10 for overnight parking). The downside of this is that there are no in-and-out privileges, so every time you leave and come back you'll have to pay for parking again.
The space itself was clean and comfortable. Since this apartment is in the heart of Little Tokyo on a main street, it can be quite loud at night. We brought earplugs though and were totally fine, however my friend forgot his the first night so he said he couldn't sleep well. If you bring earplugs you'll be fine.
We had a great time in this area and would recommend it to others. We'd stay here again in the future.
