€58k is really cheap!! I went to Miera iela, per your recommendation, its a nice neighborhood and a short walk from the touristy places. And we had lunch at a eatery which was next door to the café you mentioned. It was a good hearty basic yummy local meal served by a lovely lady who didn't speak English, but we managed 😀
As I wrote, it is a very Latvian place and usually there are not many tourists. I'm glad you took my recommendation :)
