I have been there a few times (Casanova Spa). Average-looking Asians (35 y.o.. maybe even younger), good massage, all safe services available, but no "sensual" services (like kissing or bodyslides). Massage tables and showers. Prices are above the market. Regarding high visibility: they are also legit massage place with insurance receipt and even Groupons
Been a few times. Similar to the other asian places on canotek and colonnade. Nothing special but nothing negative to say. I thought the interior is fine, definitely not a dive.
