Great price, location, and communication. It’s walking distance to the metro, as well as great restaurants and bars/beer gardens.
However, we could only give our stay 3 stars because we had trouble sleeping and that’s probably the most important part of our stay. The beds were not very comfortable (they dipped in the middle, which wasn’t great with two sleepers) and the mattress pads/covers were very crinkly and noisy every time you moved a little in the bed. The room adjacent to the bathroom also has a small window near the ceiling so I was woken up in the middle of the night when my friend went into the bathroom and turned the light on.
There weren’t a lot of things to cook with (one pot, no pan) but this ended up being fine for us because there were so many places to eat nearby.
