We stayed for 3 nights. Me and two teenage girls. The apartment was easy to find and very secure. I had a moment of panic at the first gate when I couldn't get it open. However, I figured out that I was turning the handle the wrong direction :(. Second gate was easier. Parking Permit was exactly where it should be. Parking on the street was readily available. The apartment was sparkling clean.
To help protect the hardwood floors, and to give us somewhere to get our shoes on/off, I put down a beach towel just inside the front door. After a long day, the towel was a good reminder to take off our shoes before we got any further.
Clean sheets and blankets were available for the fold-down couch. I slept on it. It was firm but comfortable. Vanya does not provide wash-cloths in the bathroom so you'll want to bring your own. Also, there was not any type of dish rag to wash the dishes or a dish towel to dry them. But there were plenty of paper towels available. There is a dishwasher, but I did not use it. No recycling container, so I left my recyclables on the counter hoping they'd end up in a recycling bin somewhere.
The girls and I walked to Universal Studios both mornings, but took a Lyft home. I measured it... it is 0.6 miles from the door of the apartment to edge of the E.T. Parking Garage. From there, it is still another 0.5 miles to the security check in of the park. It's not a hard walk, the girls never complained. We felt comfortable with our surroundings on the walk, but decided not to do it in the dark. The Lyft was less than $5.
Overall, it was an excellent trip and we'd happily stay at Vanya's place again :)
