Cheap accommodation in Rīga?

Hi, I need to stay in Rīga for 7 days in January. I only care about it being as cheap as possible and somewhat close to the city centre (also kitchen is appreciated). For this reason, I was looking for a student residence or something similar, and I found [this](https://1home.eu/rooms/?location=Riga&min_date=&max_date=) which are rooms for about 170-180€ (+50€ for utilities) a month, which would cost me as much as a week in the cheapest hotels. Could you guys give me some suggestions? If anything, I’ll just get the whole month in this residence eventhough I’m gonna be there just for a week.

Thanks in advance, and I didn’t post in r/riga cause it doesn’t have many subs.
