There are good things about the Ligotel. First of all, it's affordable and located in the heart of St Petersburg tourist area at the corner of Ligovsky and Nevsky Prospekt. The main sights (Church of Spilled blood, Kazan cathedral etc) are only 15 minutes away by foot. St Petersburg's train station along with Ploshad Vastania metro station are right across the street. A good breakfast comes with the room and is served every morning in the hotel's café. Last, but not least, the staff of young women are very friendly and helpful.
However, what others reviewers have written is true. The rooms are tiny, very tiny. There is only room for a bed, a small desk and a tiny closet. If you plan on relaxing in your room after a long day of sightseeing, or are afraid of confined spaces, the Ligotel might not be for you. Rooms are minimal and if you're looking for anything fancy, you should definitely look elsewhere. Although, the rooms are very tiny, they do have everything you need including a small safe to store your money and passport.
If you're only looking for a cheap place in St.Petersburg's tourist area and don't mind the lack of comfort, then the Ligotel might be an option for you. Otherwise, you should look elsewhere.
