"The G Hotel offered a quiet and convenient stay, with easy access to shopping and restaurants. The hotel had a pleasant industrious atmosphere, and my room was quite spacious and comfortable. I truly appreciated the many great amenities, especially the incredible shower. One suggestion for improvement would be to provide clearer instructions for locating the AC control, as I found it a bit chilly in the evening. Nevertheless, my overall experience was enjoyable, and the staff went out of their way to be helpful."

"Was just fab all around!"

"Great service and very clean, good vibe. "

"I recently stayed at the Hilton Union Square in San Francisco and had a great experience overall. The food options were excellent — high quality, well-prepared, and exactly what you’d expect from a hotel of this level. Prices were typical for a major hotel, but the value was definitely there. Parking was convenient, though on the expensive side, which is pretty standard for the city. The hotel itself was clean and well-maintained. Some areas could benefit from a little updating, but nothing that detracted from the comfort of the stay. The sky bar was a highlight — incredible views of the city. I ordered some zero-proof drinks that were surprisingly delicious, and it would’ve been nice to see a few more small-bite options to pair with them. What really made the stay memorable was the staff. Every single person we encountered was friendly, helpful, and genuinely welcoming. Their service really elevated the experience. Overall, well worth the cost, and I would absolutely stay here again without hesitation."
