It is a really great place to stay! We had a room at the top floor, it was perfect for the two of us, but frankly it would also be great for more people. The room has awesome rock'n'roll decorations which creates a great relaxed atmosphere.
Leonard is a very pleasant guy and a very good host to his place. You will feel that once you're there, no doubts about that :)
The place itself is not far from the historical center of the city. It only takes a 20-25-minute walk to get there. Overall, highly recommended :)
