Martin's friend Petr picked us up from the airport for an addtl $20. Well worth the small fee after long flight from US. We were quite jet lagged, and they respected that by being friendly but not overbearing.
Martin met us and detailed the apt./city. Lots of space and great location. nice furnishings, etc. We spent some time just people watching the square from his windows.
Martin is a great host and it is apparent he wants his guests to be satisfied. Offered anything in the refrigerator. Truly makes you feel at home.
Shower is awesome too.
2 small issues to note:
1. being on the square is great but if you sleep early, it can be loud outside late into the evening. I was tired every evening so it never bothered me. Martin provided ear plugs though.
2. It is a 3rd floor (4th for us Americans) walkup, so if you have trouble with stairs, its good to note. Not a issue with us.
Easy check in/out. Highly recommended!
