We loved our stay in Jaroslav's place, and would recommend it to anyone. It's centrally located, right next to trams and the metro, and a beautiful space that we could easily call home.
Check-in was very easy; Jaroslav sent us very detailed instructions on finding the building and entry. We loved the space - it's very tastefully decorated and the bed was comfortable. We didn't use the kitchen much, but it had everything we might have needed to self-cater. Check-out was also very easy.
We can't wait to return to Prague, and would definitely stay here again when we do!
