I didn't have any problems when I was there. However, I would watch your purses/wallets and keep them in a safe place. If you are with a tour, it shouldn't be a problem.

If u are staying at Union Square you can visit Macys Store it right in the middle and you can get everything under one roof, take a Hop on and Hop off Bus right from union square, its worth taking that cause u can see everything which my friends has listed in the above answers, the most amazing part of the hop on hop off is the Golden Gate Bridge u cant afford to miss that attractions San Francisco trip is incomplete without visiting that

All of the American coffee shops are not coffee made “premiumly” as it may say in the window. Half of these places don’t even know how to use their machines properly. I come from a coffee industry background.

Sfo hotels are not cheap unless you stay far out. Union square is a good choice and convenience . They few boutique and smaller hotel .. try Nikko or Parc55.

sí, la construcción continúa, sin embargo, según sus necesidades, las tiendas y el tráfico están abiertos. También quizás puedas traducir esto al español, pero te da noticias / actualizaciones y contacto con respecto a Union Square. Espero que esto ayude

Your in a good spot there for Fisherman’s Wharf. You will need to walk to the bottom of the hill to get on the cable car but it’s only a few blocks from union square. Security is important in San Francisco as there are strange people everywhere. Suggest if you have a wallet put it in your front pocket to avoid pick pockets and try to blend in like a local. It’s not too bad there but you will see a lot of strange people. Fisherman’s Wharf is amazing and you can get a cruise on the harbour from there. Enjoy.

Hello MariaGJS, I would suggest Sear's Fine Foods, it's an institution for good home cooked meals loved by locals and tourists alike. Also, known for their stack of small Swedish pancakes, but their other breakfast items are very hearty. As for bars: If you like craft beers, my top two suggestions would be Mikkeller Bar on Mason St. and The Golden Gate Tap Room on Powell. Mikkeller has a more neighborhood feel to the place and they also serve food, while The Golden Gate Tap Room is very inconspicuous from the outside, but inside it's a very large, lively space with a variety of games and a very, very impressive selection of craft beers. Both places have fun staff and you are sure to have a good time. (FYI: Bring your state ID/Drivers License or passport as official ID's will be checked at the door).

I think you just need to be sensible and careful especially if you are walking around alone
