Jan's apartment is lovely in a very nice neighbourhood close to shops and lots of cool restaurants and bars, yet very quiet. It was bliss to stay there during a few hot days in Prague because the apartment is very cool. The Vinohrady area is very close to the historical city center (we walked there every day even though a metro station and trams are just 5 mins walk from the apartment), yet far enough not to have crowds of tourists walking by. There is a lovely park next to the building (with a vineyard and a nice restaurant offering great views of the city). Jan's apartment is spotless!! It is tastefully furnished. I loved its simplicity yet practicality (2 toilets are great when you have more than 2 people staying there). Bathroom is really spacious and shower has the best water pressure I have ever had!! Kitchen is very well equipped. There is yummy tea (you absolutely MUST try strawberries and champaigne flavour!) and coffee for visitors. We prepared our own breakfast and supper. During lunch time we were usually out and tried different restaurants (Mexican Las Adelitas which is 3 min from the apartment is highly recommended!). Jan also suggested Zanzibar for coffee and we also loved it!
Jan is a perfect host! He thought through every single detail (there were even 2 raincoats and a few pairs of crocs in the corridor (in different sizes). I was a little bit worried because I was travelling with my Mom (who is 73 years old), but Jan met us at the train station and took us to his flat by taxi (which he didn't have to do!). He left a mobile phone with a local SIM card for us to use and we could call him any time with questions or queries. He knows a lot about Prague and Czech in general and made lots of suggestions for places to visit.
I highly recommend Jan's place and I will definitely go back there again very soon!
