On things that make you happy and that annoy you
The biggest drawback in central Moscow is the noise pollution, even at night, because you're right on the Garden Ring.
I have my favorite stomping grounds in Moscow. I love the Hermitage Garden, especially in the summer: you get a deck chair, a book and some refreshing lemonade and just cut yourself off from everything for a couple of hours. I also like Museon Park. I love Moscow for its pace of life, diversity, and beauty. I lived in Saint Petersburg for some time but I quickly got bored of it. This can never happen in Moscow.
