The location, the price and the apartment itself is worth the value for the short 4 days I was in Prague, having an elevator was a godsend not having to carry a suitcase up 5 flights of stairs. Charles bridge is a gentle 15 min walk up the road and from there you can get to the old town with no problem seeing the clock all within a short space.
The apartment was clean, the beds prepared and super comfortable if you like memory foam mattresses, the shower was great and the kitchen area had all you needed if you are the type of person who likes to cook on holiday.
Televisions were smart android TV which means we could pop on Netflix during a winddown without having to channel surf Prague tv for English stations, though the retro music channel was a good channel, with plenty of plug sockets if you've got one too many devices with you.
My only negative experience with the stay, which was probably due to it being a long weekend stay is that other people in the building seem to have no concept of noise control so consistently Friday through Monday someone was crashing around in the early hours of the morning which woke us up, though this isn't the apartments fault its worth noting if someones being loud it can be heard.
