Great value in a city where it's very hard to find reasonably-priced accommodations.
Pros: free private parking outside (for first 5 guests), clean room/sheets/towels, seamless check-in process.
Cons: a bit far from the main attractions of SanFran (although a single bus that stops half a block away will take you right to the heart of downtown Market St. after a ~40min. ride), could use a bit more detail cleaning in common areas such as corridors, kitchen, bathrooms - but definitely not terribly dirty. Bedroom was very clean for our stay.
