I spent 4 days in Prague with my friends and Vaclav's apartment was exactly what we needed to enjoy our stay. He was nice enough to let us check-in a little earlier than planned and to stay a little longer. Even though we didn't meet him, his mum welcomed us and showed us around!
The apartment was pretty close from transportations to the city center and nice cafes.
It had every commodities we needed and the room was very spacious and comfortable. Even though other people were staying at the apartment at the same time as us, we still had our space and didn't step on each other at all.
I really recommend Vaclav's apartment!
