I travel to Prague often and know the area well. This location is nicely centralized for both business and holiday travels. It's a short walk to Old Town and the Charles Bridge, and a tram to the castle stops very nearby.

There is a pub/club below the flat, but in my experience the sound is centralized at the front of the flat (under the living room/kitchen). Sleeping in the bedroom was comfortable even on the one night where there was obviously a big party going on downstairs (on a Tuesday, believe it or not). There's a pizza place on the street behind the building that is open fairly late, so that's nice. There isn't a potraviny (mini-mart) in the immediate vicinity, so that's the only real drawback IMO.

I experienced spotty wifi coverage in the back bedroom on the first night, but the hosts immediately added a secondary hub to fix the problem the next day -- I appreciated that.

The place was rather bare bones (nothing but furniture, kitchen supplies, and towels -- no plants or other "homey" items, so keep that in mind. It's a very minimalistic apartment with large closets and modern amenities (for example, the TV has an HDMI port, which is somewhat rare in Prague apartments)...
