Aika and Maxim run a very nice, friendly, and clean property. They were easy to get in touch with and were nice to chat with. The location is fantastic as it's just a stone's throw from the main attractions in Williamsburg.
You should know that it is an older building, so if you need a super-modern property, this probably isn't for you. But if you want a nicely run apartment that is seen less and less in NY, I highly recommend it.
PS. The subway noise wasn't an issue for me, but you can feel it rumbling underneath the property from time to time.
