The flat is comfortable and very well equipped - we could find absolutely everything we needed. The location is great for tourists too. All the main attraction are just a short walk away, there are lots of restaurants around and Rossia station is just 5 min walk. The trams pass along the street till late night but we use earplugs and it wasn't a problem. The only thing in the flat was the smell is sewage in the bathroom but hopefully it's easy to eliminate. We still enjoyed our stay.
