My partner and I stayed here for a week and it was delightful! The place is truly cozy but doesn't feel too small. Very convenient location in Berkeley for our purposes. Also, David is a wonderful host. He was very responsive and was flexible with our check-in/check-out once we communicated with him.
David was great about answering my questions and handling any issues (the power went out briefly and he was on it). There were nice flowers for us upon arrival and everything was as it appeared in the pictures or better. The walls are a bit thin, so you might have to be a little careful about the noises you make. Downtown Berkeley and BART are just a short walk away.
David is very well communicating. Everything went really smooth. We enjoyed to stay in his apartment because we were close to downtown Berkeley and 4 of us could fit comfortable. The upstairs neighbor was loud but it's not David's fault. He also gave us a parking space on the property. I recommend this place!
