My husband and I stayed at the Hotel Fusion near Union Square in January. The rooms were very clean and stylish; but the walls are thin and let in sounds/conversations you may or may not wish to hear at 2 a.m. The room also got stuffy but opening the window helped. Only stay here if you are a sound sleeper without young children.

This hotel might have been okay until the moment I stepped into the bathroom and found a used CONDOM on the floor. It was horrifying. When I made note of it to the front desk the woman working said she would have the manager get in contact with me (mind you they still charged us for our stay with them), and I still have not heard anything back. Anyone have any suggestions?
In addition, if you have a car and you valet expect to wait 20 minutes before they bring your car around. If you have plans to be at the airport, their method is not very efficient.

The location of this hotel is great. It's only about two blocks to the BART and Powell St. Station, which is an easy way to get there from the airport.

The room was decent. I liked that the door to the bedroom closed separate from the entrance/bathroom area. That was nice for sharing with a roommate who might come in at a different hour than you.

They have Internet, but bring your own Ethernet cable. Otherwise, you can pay for one.

The main complaint is that the hotel is next to a nightclub. It wasn't too noisy, and some of it is to be expected with the location in the middle of all the action. However, I'd say staying on a weeknight would be better than a weekend because of that. The music wasn't actually that bad, but the lines outside the club were long on Friday, and you could hear the people.

Considering this and the room that some of my other colleagues got at different hotel for a better price, I'd say it depends on the deal you find and whether you are staying on a weekend or not.

Ok, it's not the Hyatt, or the Nikko, or the Hilton. It doesn't have the fancy restaurants, big rooms, etc. It does however have a great staff, clean rooms with great water pressure in the shower, modern amenities (lcd tv's in rooms), etc., and costs about half what those other guys charge.

Ok, so it doesn't have a restaurant. Dude - you're in Union Square - walk out the front door and you have about 100 different restaurants to choose from all within walking distance.

I do have to take away a few points for putting the ethernet jacks on the opposite side of the room from your work desk. But, that's why they call them "laptops," so not a deal breaker.

Having no a/c could be an issue in the summer, but in March it did not matter. Union Square offers a large variety of brand hotels, along with many historic independent hotels. The latter category includes some less than savory selections. Fusion is a good choice though, and if you're on a budget (and who isn't these days), this is a very good bet. Splurge a few extra dollars to get the upgraded rooms (i.e. Dlx King or Jr Ste) and you'll be in good shape.
