We loved our stay at Courtneys place. Courtney answered all of our questions within minutes and asked us several times if we needed anything.
The flat is nice and spacious, a cozy bed and a lot of small details.
We didn't have a car, so we took the Bart to the city. The walk to Bart is about 10-15min and from there it's a few minutes with Bart to the city. At night we mostly took a Uber to get home. We felt safer that way though Courtney told us the neighbourhood was totally save.
