Everything is great: location, communication, check in, amenities. Except one thing: sound proofing is almost nonexistent, so the sound of someone simply walking up the stairs or around their apartment (above or next to the one I stayed in) is enough to wake you up, and I'm usually not that picky and can sleep well.
I guess I was unlucky in a sense that units above/next to me were occupied too and they stayed up late/got up even earlier than me.
