I stayed at this place for almost a week and I must say I enjoyed it. Also about Josef, he is one of the best hosts I saw on Airbnb. Before coming he had already given us a lot of information about the neighbourhood like restaurants to try, things to do, groceries where can I buy the best things in the market and very important thing he gave us kind of route to cover all the tourist spots in Prague.
Pros:
1. Location is very close to Old town square
2. Apartment is big and renovated.
3. You have internet and smart TV
Cons
1. Since this apartment was being set up few things were missing that were mentioned in the description like child chair, coffee machine, child cutlery, washing machine etc. But Josef was proactive in resolving most of them.
2. House is not that soundproof because of which I could hear some construction/fixture fitting sound from the next room. But i believe this is just the time being.
