Rob was very kind, offering not only his apartment, but also sharing tips and suggestions on places to go or to eat out, in order to avoid the tourist traps and live a better Czech experience.
The area is also nice, most residential but with cafes and restaurants in the same block or aroud the next one. The center is reachable in 10 min by foot. We basically walked all the time, without never using the public transport. I recommend it!

Thanks so much for the hospitality and thank to Stepan as well, for the nice and warm welcome.
