Casa Leto is a small and exclusive private hotel, centrally located near to the Hermitage and St. Isaac's Cathedral and catering for the sophisticated business and cultural visitor to St. Petersburg who is looking for something more atmospheric and individual. The hotel occupies a floor of a 19th century building on Bolshaya Morskaya, formerly know as 'Diamond Street'.

The interior of Casa Leto echoes the building's 19th Century origins. The original plasterwork has been preserved and the same luxurious space and proportions respected. The entrance to the hotel has an impressive old staircase. The large individually styled rooms are classical and evoke the atmosphere of St Petersburg, with high ceilings, plasterwork and antiques.
