We had a wonderful wonderful stay at Monika and Jaroslav's! They are great hosts and were very responsive.
Their apartment is close to everything! Public transportation, nice restaurants and cafés, cute shops... The room is exactly as pictured: huge, well decorated (and very comfy!). It may be a little noisy during the night for people who aren't used to cities that never sleep, but since we're from Montreal, it wasn't a big deal for us.
We would definitely stay again at Monika and Jaroslav's!
