Perfect for a leisure stay in Berkeley. The guest house is well thought out and sparkling clean. The area is very calm and quiet, though just minutes walking to the lively Elmwood and Rockridge area.
For a stay where one plans to work a little bit remotely (which I tried), however, the wifi is very spotty/unreliable and not suitable for professional use if needed. The bed is nice though it sags in the middle. No big deal, but if you are sensitive to that it is worth noting!
Loved my stay at Celina's and would happily return!
