My partner and I had a great stay at Zita's. The space is smaller but still comfortable, and has all the amenities you need for a short stay. There was no sink, but the fridge had fresh water stocked in glass bottles for us. The bed was comfortable and accessing the private bathroom was no problem (right next to the room, just out the door and a few steps around the corner).
Zita was awesome with communicating - our arrival time changed a couple of times, and she met us when we arrived and showed us everything we needed to know. Very cute spot and nice neighborhood, only slight downside is that it takes a minute to get to downtown Berkeley or Oakland, if those are your destinations. The bus is just over a block away though and takes you straight there (or to DT Oakland/BART) - or we took some of the Lyft bikes that were nearby too and it was a nice 20-minute ride or so to DT Berekely. There are some nice restaurants and other spots nearby though, we got a great breakfast at Paradise Park Cafe and a treat at Donut Farm :)
