We had a wonderful stay at Guyot business boutique hotel. We couldn't be more pleased. The location is good : take the bus one to two stops to Petrogradskaya metro station and then it's only two metro stops to Nevsky prospekt/ centrum.
The room was spacious and the bed bug and very good so sleep in - not too hard and not to soft. The bathroom was nice, with a bathtub. The restaurant at the hotel offered good and very varied food . The prces were good and cheap for us from a Nordic country, and the hotel even offered discounts to the hotel guest - that meant even cheaper food :-)
They had a nice spa room that was private and the hotel offered 1,5 hour there for free with the reservation.
We booked room with half pension and were pleased with the food.
The breakfast buffet was also nice with differing hot food every day . I have seen a more varied breakfast buffet elsewhere, but it was satisfactory for the price we paid for the week there.
The hotel staff was nice, some of the staff had some difficulty understanding English - bit with today's translation apps it was ok.
The hotel had nice decor and interior and have a "honey" feel and didn't feel to big or "commercial" which is their best asset I thinkthe staff were very friendly.
All in all we had a very! pleasant stay bad I highly recommend this hotel.
