I'll try to write a very honest review and hope it will help future guests.
The apartment located in the very good area- you can fine anything you need nearby:markets, pharmacy,subway,huge shopping center with restaurants and coffee shops in it, banks. Right behind the building there is a nice children's playground, fountains. The neighbors were very quite and we didn't hear any noise at all. The size of the apartment is good enough for a big family, bedrooms are pretty big (like at the pictures), kitchen and living room are good sizes as well. There are many cabinets, shelfs and hangers for clothes. The apartment has pretty everything that a family may need during the stay.
Minuses: before we came to moscow i sent an email to the host that its very important for us that the apartment will be clean since we will come with a child. But unfortunately the apartment was really dusty, the floor was dirty, the kitchen cabinets were dirty, oven, microwave, you name it. The towels and bed sheets didnt smell clean (as if they didn't dry well after the laundry), the floor is made from cheap material and little parts of it come off every time you walk here and there (so you can see those little parts on your socks). The toilet seat was broken and no one came to fix it during our two weeks stay there. There were four or five chairs by the kitchen table, and three of them were broken.
I would give this apartment 4 stars only because of its location and size, otherwise it would be a 2 star place. If you don't mind dusty rusty place, you would like it there.
