Alex is a great host, even though we never met him, he was very clear with directions and always available for help! He even called in a reservation for us since we didn't have cell service.
The apartment itself is as described. Noise level depends on who else is staying. We had a very loud person in the room next to us talking on the phone at 330 in the morning really loudly. But after he left it was better. It's a great location and good place to stay if you want a hostel-esque vibe.
