David's apartment was consistent with the description: barebones. Four single beds in a big bedroom. That's what we needed, so we were happy.
The pin and address in the description are wrong (10 July 2017 as of writing). The address is actually Bělehradská 443/76, 120 00 Praha 2-Vinohrady, Czechia.
Communication with David was a little difficult. We were never told what to do for check-in and check-out, and David never proactively told us what to do. However in the end all worked out fine, and really that's what counts.
The location was very convenient since we were interested in visiting the old Prague as well as other parts of town.
We'd go back to David's and recommend it to a crowd that just needs a place to crash.
