Very nice host with prompt response.
Apartment is great, 4-5 mins walk to Charles Bridge (Karluv Most) and National Theatre (Narodni Divadlo), suitable for opera lover and / or tourists. Night life is close to the apartment.
8-10mins walk from Staromestska station, sounds a bit long but you can find many different things during the walk.
Inside the apartment, got everything in the kitchen, so I can cook all meals. This is what I love.
I do highly recommend Jirina's place :)
