I didn't get a chance to meet Emil, but everything was well arranged at the time that I arrived.
I got to the office (5 min by walking from the main station) to pick up the apartment's key and card.
The place is very organized, clean, neat and bright. It was perfect for our stay at Prague. The best way to get there, is by subway (Namesti Miru Station) and walk for 5 min.
I strongly recommend Emil's apartment.
