We stayed here for 3 nights, it is an easy 20-30 min walk to the tourist area of the city and the hotel provides a free shuttle bus in the morning and evening which is really handy but a little difficult to find the first time round (directions below). The area is a little run down but we felt safe enough walking around even in the early morning and later in the evening. As it is off the usual tourist route it was nice and quiet in the evenings and seemed more 'russian authentic' which was nice. The staff did not speak much English but were very nice and if you get stuck their sister hotel has English speaking staff you can call. The breakfast was excellent, lots of fruit, veg, cheese, meat, bread and cakes. The restaurant food was good but a little pricey compared to what you pay in the centre. The beer is good! The only down side is that the hotel rooms are not airconditioned and it was hot while we were there, but you can safely open the windows (mosquito mesh and a lock) and they do provide an electric fan. The room and bed were very comfortable and the bathroom was clean and had a good shower.
How to find the shuttle bus - with your back to sennaya plochad metro, cross at the pedestrian crossing towards the K3 bus (this goes to and from the airport and is really cheap!) turn left and walk along the busy road past all the little shop booths, at the end of the booths turn right towards the waterway - you will see yellow K1 buses, cross the little black bridge over the waterway and look for the minibus with 'Amaranta' written on the side which comes every 30 mins on the hour during operating times (check the hotel website).
Note - The city sightseeing tour does not run between 12 and 2 each day, we did not know this and spent an hour waiting before giving up and walking (which was probably more fun anyway!)

I stayed there with my bf just for one night but I loved this small hotel. The building is quite old but it was renovated totally. It's located on the small island close to the Mariinsky theater (10 mins by foot). We got a small room on the first floor. The size of the room approx. 12 m2. But it was very nice decorated with some paintings on the walls. The bathroom comes with shower.
The breakfast was included in the price (by the way, the price was 20 euros for 1 night). Choice of dishes was good and the quality of food was ok. I can reccomend this hotel.

Most of the comments complain about the distance from the centre of St. Petersburg , but even in very cold weather (minus 25° Celcius and an ice cold wind) we didn't mind walking . It's about 2O minutes to the Izaäkcathedral . Even if you don't like walking , you can take the shuttle from the hotel . In our case was it impossible , the shuttle didn't start due to the cold so we had to walk on the only day we wanted to take it . No worries !
The only thing is that the staff is mainly Russian speaking , only some of them know how to communicate in Englisch , but they are not always around .

The receptionist who greeted us (I use that term loosely) was scary, our rooms was ok well furnished but a little dark. The breakfast had a fair selection. Wifi reception was spotty.

My main issue is the location, I knew it was out of the centre, but it is quite far away and the shuttle bus only takes you half way in towards Nevsky and it doesn't run all day just first thing in the morning and in the evening (several times). When we wanted to come back midday this meant a long painful bus journey, if you are organised and don't mind being out all day then this won't be a problem.
