My family and I ( 4 of us ) stayed at Martin's place at the end of August. Martin was very helpful and even had a taxi waiting for us at the airport. He gave us important tips like where to exchange money -- vital information, as some places in Prague can change you absurd commission fees.
Our room was spacious even for the four of us. The location was superb. Close to all the excitement, but tucked away, so we were able to have a good sleep.
Prague is a breathtaking city, and Martin's place is the perfect location to enjoy it!!!
