we loved our stay in Josef's apartment. straight away he offered to arrange us a private transfer from airport to the apartment and the driver even saw us into our apartment and unlocked the lockbox and door for us.
the location was perfect! everything you would need was within ten minutes walking distance and it was a perfect central location to get to everything we wanted to see.
the apartment itself was lovely, lovely decor and the bed was huge and very comfy!!
the apartment was through a shop which confused us at first but there was no issues and it was handy if we wanted a snack!
the corridor outside of the apartment can be very loud at night if other guests aren't being quiet, I would recommend taking some ear plugs if you are a light sleeper. this is the only issue we had with the whole experience.
I would definitely recommend and stay again if we were ever in Prague
