Martin is a wonderful host! He met us even earlier than i've informed him, showed the underground parking place and made a tour of the apartment.
Only one thing to mention, underground parking is paid with 10 € per night in case you have less that 3 nights stay. The apartment itself is in a new building, super clean, very comfortable and well equipped. The location is amazing, and everything you could possibly need you can find it nearby. He gave us some good tips. Check-out was very fast, as we only left the keys in the room and just closed the door. If you need to go to Prague, Martin's place is definitely the greatest one.
