I stayed here with my friend from 27th to 31st Aug 2013. We were absolutely delighted with the comfort and service we enjoyed. In particular the reception staff who all spoke English were at all times very friendly and helpful. From visa support and pick up at the airport to arranging a private tour and organising room service, all our needs were met. The room and bathroom were a decent size, the beds were very comfortable, the shower was terrific, there were complimentary toiletries, tea/coffee making facilities, BBC World News on the tv and every morning a terrific breakfast . Previous reviewers have mentioned the traffic noise but in fact it was fairly subdued. However if you are a light sleeper you should request a room at the back.
I should also mention, because I was thrilled by it, that this hotel is so tastefully furnished that I felt I was staying in a very exclusive boutique hotel.
Location is about 10 or 15 minutes walk from the centre, a very pleasant walk over two bridges, and just across the road from the Peter and Paul fortress. If I were ever to return to St Petersburg I would definitely stay here again.
