Coming from the U.S., we were a bit overwhelmed about all the warnings and legalities related to getting and registering our visa. Natalia was fabulous about it all although didn't really front load the information to us - which is why I am telling anyone thinking about the apartment not to worry, just ask and she has it under control!
Don't worry about the stairwell (dark and worn) or elevator, the apartment is quite nice and VERY convenient. A grocery store is in the same building, a bank just down the street, a primary subway 2 blocks away and a range of fabulous restaurants really close. One of our favorites for breakfast was maybe 3 doors down from the underground entrance to the subway - lower level. Cafeteria-style, the best potato pancakes anywhere - for about $2 a person!
Not a bad walk to anywhere! Absolutely loved our stay and loved where were were!
