1) Hotel Oktiabrskaya 10/118 is roughly twice better than Hotel Oktiabrskaya near Moscow railroad station
2) It is not really 4 star hotel, it is more like 3 star budget hotel.
3) got a quiet room near the backyard, so noise was not a problem
It might be a very nice hotel/price if you know exactly what you will get and what not.
pro: 1) nice location, specially if you will have to travel a lot: ( subway station "Ploshad' Vosstaniya is a cross-road of many subways lines)
2) large room, so you could relax in your room
3) very nice cleaning service
4) Nice building
5) Huge food mart Stockmann is 5 min walking near the subway station
6) room have a small fridge
7) Plenty of nice place around for food
con:
1) small beds, so you better order 2 beds to have a nice size bed to sleep
2) no coffe-maker in room
3) small-old TV~ 20 years old
4) no WiFi in the room, even for $
5) Heavy smell of smoking in the building and in my floor (I had the non-smoking room)
6) There are only one person ob front desk. If group is standing before you, you could easily spend 1/2 hours before get any service
7) Bar in lobby is small and have only smoking place
8) you better do not use Shampoo and soap which will be in your room
Overall: if you really after comfort which can be provided by typical 4star US hotel, I would advice to stay in new Marriott Hotel in Vasilyevsky islend, near Black river (Chernaya rechka), 10 min walking from Vasilevskij ostrov subway station. It really fit all American standards for ~ 1/3 increment in price compared to Octyabrskaya. If you have a family vacation, or romantic trip, and could afford this, do not stay in Octyabrskaya. However if you like to save and still get a good quality for your $, Octyabrsaya would be in the priority list, as there are many hotels in St. Pit which does not provide even such basic comfort.
If you are enjoy to stay in creepy hotels like "Holidays In" in Manhattan, you would be absolutely in love with Octyabrskaya hotel. I have a short business trip, with limited funding and I was pretty happy with what I obtain per modest price.
