Anastasia,s place is perfect for a short stay for a couple. This studio flat is located in a charming quiet area, much more quiet compared with the city center overrun by tourists. You can find here some nice options to eat which are not tourist traps like most places in the city center. Metro station is very close and you can get to the main spots very quickly, which are only 3 stops away.
The apartment is nice and clean, looks quite new actually. The railway nearby is not an issue, y cannot hear the trains much. Generally it is quiet around. It is very small though, so do not plan to cook large meals here. For us it was fine as we have stayed for only 2 nights and mostly ate out. For the price it was an excellent deal!
