I would like to say "Thank you" to Simon for his warm welcome at his apartment.
We stayed in his apt for 3 days and it was good - the apartment was clean, well furnitured and everything worked.
The wi-fi connection was quite good as well.
The Praha-2 (Vysehrad) disctrict was OK and the apartment has a lot of public transport nearby (tram station in 1-2 minutes and metro station in 5-7 minutes). There were some shops nearby and some restaurants as well.
I can recommend this apt to everyone and would like to come back here in the future.
