From the images it might seems a big room but it was infact a mid-sized room. However, the cleanliness and availability of daily amenities was on the spot and I had no issues with my stay.
It is a 15 minute walk to Coliseum BART station and while it feels safe to walk during day time, I would advise taking a Lyft/Uber for night travels. The place is located at the dead end of the street and it gets dark over there.
