"The hotel is a boutique hotel. Actually, there are two buildings behind the Catherine Church: one called Catherine Palace and the other Catherine Arts. They are operated by the same company, and the front desk is also the same, with similar prices. If you want a room with a view of the church, I recommend Catherine Palace. Regarding room types, if you have two large suitcases, be sure to book a comfortable room of 20 square meters or more. I booked a room of 20 square meters or more, which was generally okay. The bathroom was a bit small, and the plumbing was quite old. I stayed for three days. As for the smell that some people mentioned, I think it's because the hotel uses some kind of disinfectant that doesn't smell very good. Also, the hotel is quite deep, and the ventilation isn't very good. The lack of exhaust in the bathroom might have caused some odors. I opened the windows to ventilate during the day when we were out sightseeing, and there was no smell when we came back at night. The hotel has an excellent location. It's right next to Nevsky Prospekt, next to a metro station, and diagonally opposite Kazan Cathedral. The hotel breakfast is also very good, with plenty of hot food, vegetables, meat, eggs, milk, porridge, and fruits. You can eat your fill and go out. The only downside was the hotel's Wi-Fi wasn't very good. My Honor phone couldn't connect to the network, but my companion could. I don't know why. We had to use our own mobile data. Check-out was super fast, and getting the check-in certificate was quick. Overall, it's an average hotel, but it's relatively affordable on Nevsky Prospekt."
