It was very pleasant staying with John, the apartment is modern, clean and conveniently located! John was helpful although we had already been in Prague for a week so we didn't require any extra information john left his mobile number in case we did. The only real issue with the apartment was the light in the bedrooms is pretty bright so we had to fix a scarf to them to block the morning light out, but apart from that the stay was really nice! Would highly recommend!
