Easy to find with Maps. Buses run at all times. It's a good 25 to 30 minute walk, but it's quicker than taking the bus. I would recommend a taxi to get there as it is very steep. The location is very nice and quiet. Check-in was easy and you quickly find your way around the apartment.
There were a few things in the stairwell, but it didn't bother me personally. The room was clean and was as described in the ad. The kitchen has everything you need.
