With St Isaac's Cathedral practically on your doorstop this hotel gets a big tick in the location box. On some websites the Petro Palace gets a five-star rating but we feel it's a very good four-star. There are 195 rooms (superior overlooking the inner courtyard, deluxe and executive) over 8 floors. Rooms are generally spacious with good facilities and the all-important tea and coffee accouterments. The hotel has an American Sports bar, lobby bar and an Italian restaurant on the top floor. The hotel also has a small pool, sauna and gym.
