I am looking for hotel recommendations in Hamburg's St. Georg area. Would like to keep it at or under $200 per night. Thank you!

you do not say when or facilities you wish for. Which dollars are you writing about?
Suggestions with reviews.

We will be there May 31 - June 5 and would like to stay in the St. Georg area. $200 American, so right around $180 Euro.

We stayed in Hohenfelde in 2016 - this is the district next to St Georg. We stayed some way out because we had a car and didn't want to be in the city. Our hotel was the Holiday Inn Express Hamburg City Centre, and it was very good value for money. The rooms were not enormous but the price was good and breakfast was part of the deal, and also parking was free. There was a supermarket right next door. It could be that you were looking for something a little more central, and this wouldn't be it, but if you are just looking to be out of the centre then you could have a look at this hotel.

Euro is not abbreviated $...

I know. That was a typo.
