What a neat, enjoyable experience! This was a great alternative (with a much lower cost) to staying at the convention hotel (Hyatt) that was an easy 8/10th of a mile walk down Kettner St. (The $2.50 trolley is super-close, too.) Picking up some groceries and beverages at either of a couple nearby markets cut my costs even further.
The Dutra, and my room R, is a unique and rather funky place ...kind of hip; kind of European. Kind of noisy, but I lived several years in the heart of Chicago, so it actually felt good to be immersed again in that environment. After the first night's adjustment, I slept great. Carolina is an excellent host as she reached out frequently.
I four-starred the check-in only because I couldn't get a link to open on my phone and it took me a while to figure out that four of the units enter in the back of the building.
