Jaroslav place was awesome! Right next to the National theatre, Dancing House and river Vltava. His assistant Katka met us at the apartment and showed us around. It was 3 of us staying in the place, so we needed 2 sets of keys (my brother had other pans the first night, so Jaroslav was willing to come later and let us borrow his 2nd set of keys for one day). When he stopped by, he was very helpful to answer all our questions about the city. We had a nice conversation.
His place is very spacious with 2 small bedrooms on the 2nd floor. Bottom floor has a nice bedroom with king size bed and big kitchen with everything you need. We used it a lot :-) Living room is huge - includes 2 couches and 1 big dining table. Now the best part - the view! It's really spectacular - you can see the Prague castle, Vltava river, Charles bridge... beautiful. Other windows allow you to see National Theatre.
I forgot to mention that the kitchen has a nice outside patio where you can sit and relax after walking all day throughout Prague :-)
Jaroslav's place was awesome and he was a great host.
