Adam is a great host. The room is very large and the flat well equiped. Something to note is how good the heating is. Our last night in Prague it was freezing cold outside (-14) but inside the house and the room it was cozy and warm. We were also provided with a SIM chip with data, wich was really helpful to navigate arround the citty.
If you are going to Prague, I can't think of a better place to stay than Adam's flat.
