Just ran a quick check...
Site looks relatively legit - nothing too shady there. They have a pretty long list of "prohibited" customers and foreigners aren't listed among them. That doesn't necessarily mean they're foreigner friendly, but it is a good sign.
No reviews of the shop itself on Kakubutsu (big Fuzoku ranking page) but there are three reviews of girls from there: 65, 65 and 38 out of 100 but they're from like 2013/2014 so I doubt it has much bearing (for good or bad) on their current level of service.
Fujoho has quite a few reviews up - quite a few pretty good, some not so. You can check them out here:

Sorry that I can't give any firsthand info - from what I can see via a 5 minute net check it looks like a decent shop somewhat on the cheaper end of things.
