Absolutely worth what you pay. The free room upgrade may be influencing my decision a bit, but the 'standard' rooms looked just as comfortable, only smaller. Bonus points for lovely gesture from the staff for gf's birthday. Breakfast in the room if desired at no extra cost. Tea and ice-cream at any time to the room at no extra cost. Discounts for some nearby restaurants available from hotel. I mean, wow!
If I had to be critical, I would have a few qualms over the quality of some breakfast ingredients, but that may just be me being picky in terms of taste preferences. However, this did not affect the quality of my stay. Indeed, for the price paid, value for money was through the roof. Really, all very impressive. Would (will!) stay again, and recommend to all who want a pleasant, comfortable, well-looked after (only if desired, of course) stay.

I did not end up staying at this lovely hotel, but I must praise their staff/service to the skies. I arrived in St. Petersburg late in the evening and was "stood up" by my Airbnb host. As I was trying to figure things out, I wandered into this hotel to ask for help. The receptionist, Марина, was so incredibly kind! She worked through my language barrier (I don't know Russian at all), she set me up with wifi, made a phone call for me as my phone wasn't working, and since, there wasn't availability in the hotel for that night, called around to neighboring hotels to find vacancy because she didn't want to send a lone, young woman out wandering at night. I can only imagine their service must be phenomenal!

Big thank you for Olga and the staff, they made us feel very welcome.
Great service and very friendly people. The rooms were comfortable and clean.
Breakfast is in your room or the lobby, you can choose which time.
The Nevsky Prospekt and metrostation is a 10 minute walk from the hotel, it's also
a small walk to the Moscow trainstation, where you van take the Sapsan highspeed train.
I would definitely come back!
