The apartment is conveniently located 10 minutes walk away from Praha HL (main railways) if you are connecting to other cities. It is also across a metro with a few tram lines nearby. The old town is a few minutes walk away, making all attractions within walking distance.
The apartment is also as you see in the photos - large and spacious with 6 beds (and a sofa bed for a small person perhaps). Communication with host was also very efficient.
Only issue is if you are a light sleeper - it can get noisy at night. I could not really tell if they came from apartments across or the pubs below but both sat and sunday night you would hear loud laughter and chatter even till 6am in the morning.
With that said - heavy sleepers will have no problems and I would stay here again, but with earplugs :)
