Andrea is a super generous host, and we had a great time staying in our little suite with our 8-month-old baby. We wanted to explore the area car-free and this was a perfect location for that - lots of great shops, restaurants and cafes to get to on foot, and a great walk around Lake Merritt to the Oakland Museum and Wild Child. It was also a great jumping-off point for transit-based adventures into SF, like the aquarium and exploratorium.
The space was a good size for two adults and a baby, and Andrea set us up with a crib, baby toys, high chair and everything we would need to have a good time - but I do think it would be cramped for any larger families. It's a clean, comfortable and fairly minimalist space. There's only a microwave for cooking, but we managed well enough with it (did you know sweet potatoes cook really well in the microwave? I do now. 5.5 minutes.) and lots of places will deliver there, as well as grocery stores and eateries in walking distance, if you don't mind some big hills.
It was a big deal for us to travel with our infant for the first time and Andrea's hosting and this sweet little suite made it delightful, beyond our expectations.
