Easily, but it takes some time.
The international flights come into St. Petersburg Pulkovo II airport.
You can get your own taxi there, but it is expensive, often they ask $50, or even 1,500 rubles.
If you have only a carry-on you can catch a minibus to Sennaya ploschad or to the Moskovsky Metro station and ride metro.
But it is difficult to carry large bags on public transportation.
The best way is to get a private car. It will take about an hour in the afternoon to reach the center and cost about $15-20 or 500 rubles.
If you stay at one of our apartments we will be happy to arrange to meet you at the airport and settle you in your apartment.
