We had an amazing time in San Francisco and Judy and Ed and their place were a big part of it. The location is perfect. There are two bus lines very close by that take you to the subway station to go downtown. If you time it right, it is a 35-40 minute trip. Both the bus and subway are included in the MUNI pass. It was about 30 minutes from the airport and if you feel adventurous you can take the train (not included in the MUNI pass) from the airport and then take either the bus to their place or take an Uber. At our arrival Uber was $30, leaving, it was $43.
Judy and Ed are very kind people and they will make you feel welcome throughout you stay. The place has a dining/living room which is very spacious and has a very nice view of the city. It also has a kitchen which has what you need to prepare breakfast, etc. The bedroom is small and the bathroom is small. The bed is on the soft side but comfortable. I sleep on a firm bed and I had no trouble sleeping there.
Judy and Ed really makes you feel at home. They were responsive to questions about the place, the neighbourhood, the city, etc. At check-in they will go over everything plus information about the city, what to do what not do, etc. There is a grocery store and some restaurants 5 minutes away. We rented a car at Enterprise and Uber was $12 to go there. You can also take a bus there. We felt very safe around the neighbourhood and on the bus/subway rides.
We are glad we stayed at Judy's place because it was close enough to the city centre but had local attractions and nice restaurants close by as well and it was bigger and cheaper than staying closer to the centre. And above all, because we had the fortune to meet such kind and thoughtful people as Judy and Ed.
