I really enjoyed my stay with Gloria, Henry, and Nicki. The room has a comfortable bed, a large desk, and thoughtful touches, like a towel rack, a nightstand, and several hangers in the closet.
I also liked the bathroom, particularly the shower/bath. The water pressure is decent, and it was simple to adjust the water temperature.
The only thing I didn't like was that the Wi-Fi was sometimes intermittent. The simplest way to get a signal when a signal didn't seem to be available was to turn off the Wi-Fi on your device and then turn it back on. I'm not sure this method works every time, but it worked many times.
Overall, though, I would definitely would stay with them again if they would allow it.
The walk from their place to the nearby 19th St BART station is along Lake Merritt, which is one of the treasures of Oakland. It was really nice to walk that path as part of my commute during my visit. Nearby on Grand Ave are several restaurants, which is convenient should you want to get a bite to eat.
