The Hotel Intervarko is a pretty nice hotel. It's off the beaten path but it's right next to a bunch of public transit and not too far from a public transit center of Alexanderplatz. It's easily walkable or via public transit. It's easy to get to and from Berlin HBF to the hotel. There's a cute little graveyard nearby and a cute cafe that serves amazing food. The hotel doesn't seem to have controlled temperatures which was problematic for the temperature that I was in during my stay. The staff were very nice.
