Email from Mosa with entry instructions made it easy. Never had a chance to actually meet but no problem being in touch via texts or email, and we knew she was occasionally home in case we did need personal contact.

Nicely done converted garage in nice (and quiet) neighborhood, very close to visit our son and family, the purpose of our visit. Clean and roomy (I did an hour's worth of yoga the last day we were there). Nice touches with dark chocolate kisses (went well with the Merlot!), fans really helped on the two hot nights, with open screened windows for ventilation/fresh air.
Would like to stay again next time we visit family in Oakland.
