I'll start off by saying that I would highly recommend (and have already recommended) the Union Street Inn to anyone looking for a classy and warm stay in San Francisco. It's a bit expensive, but worth it. The people were very friendly, the place was gorgeous (with character!), great location, and fantastic food. My husband and I stayed here for our wedding in the Marina District. It really was perfect for us and for the occasion.
A few highlights: The morning of our wedding, I went for a long run and was back too late for breakfast. But without my asking, one of the kind owners made my favorite breakfast... she knew I would need it for the day ahead! This really helped the day start off just right. Later on, I got ready in the room with my bridesmaids and mom and photographer. The room (and garden) were the perfect setting for our wedding preparations (and the associated photos), and I will forever have very fond memories of this time.
That being said, there was a big stressor that I feel I should mention. Months before we stayed at Union Street Inn, we booked the room and were in contact with the owners. I had asked if it would be okay to store my wedding flowers (5 bouquets) in their refrigerators. They deliberated over this, then gave me a very enthusiastic yes (with many exclamation points). I thought, great!, I don't have to worry about this. But when I arrived the day before our wedding with the flowers, the man who greeted me had no idea that they were meant to store them, and the woman (who would later cook me the amazing breakfast) was quite distraught and rude about the situation. She almost broke my bridal bouquet by trying to shove it into a tiny beer fridge. I was almost in tears, as this was very stressful for someone with a lot on her shoulders who thought she had arranged a good solution months ago. In the end, we stored the flowers in the garage, and they were kind enough to give me a mister to keep them hydrated and cool. Tensions softened, and the rest of the stay was great, but I did have my doubts in that first hour.
