Mango na Kazanskoy Guest House 

Let me preface this review by telling you: This hotel is not for those seeking spacious rooms or continental breakfast. Where it is: The hotel is very near the city centre of St. Petersburg, you don't need the Metro or any public transport. In addition, you should walk anywhere you can anyway, so you see the beautiful architecture. What it is: A hotel for the small budget and for those not fearing to come in contact with other guest in the "restaurant", which serves as a place where you have reliable wifi and can get a coffee any time of the day. The staff: Friendly, kind and always with a smile. The verdict: If you need a place to stay in St. Petersburg, don't expect luxury and are willing or able to walk, then I would totally stay there
