Petr's place is in an excellent location for touring Prague. The #22 tram (which goes direct to Prague Castle) is very close, as was a Tesco for making meals in, and even a unique WWI museum. MrParkit is also just around the corner if a car is needed for temporary off-street and secure parking (it's shared with the Ibis and Novotel hotels, though.) The flat has enough space for 6 or more people to eat and sleep but not really any common room to chill in (though there is a small table upstairs with small bean bags (?) and games for kids). We arrived from the airport late and Petr kindly arranged for a key hand-off from a local bar. A definitely adequate place for our short, two night stay in Prague.
