So, this is a tough review to write :-) A lot of conflicting viewpoints. But here goes:

Marco was warm and welcoming. Really nice. In fact, my sister and I were a bit lost and he came to meet us where we were, about a 10 minute walk from his flat. We thought that was really thoughtful and nice of him. We enjoyed walking and chatting with him.

The room is exactly as pictured. Clean, comfortable. No complaints there.

So, Marco was great. And the room itself, good. Clean and comfy.

A few pretty big negatives though. The kitchen was DISGUSTING. There were pots and pans filled with old food (which remained there the entire time we were there), flies everywhere, the sink was full of dirty dishes, it was dirty, just really grimy and gross.

The bathroom was ok. Not the cleanest, but alright. Good enough. Though Marco did allow each of us to borrow a towel, as we had forgotten to bring our own. So that was really nice too.

The guys who lived there were quiet and respectful while we were there. No issues :-)

If anyone has an issue with marijuana, they shouldn't stay here. The second Marco welcomed us into the flat and left us to our room, he joined his roommate in the living-room where they proceeded to smoke pot. Marco tried to hide this from us when we came in to ask him a question. There were also jars of marijuana in the kitchen, and our bedroom smelled very faintly of stale smoke.

And finally, Marcos roommate (didn't get his name, as he never introduced himself), was slightly off-putting. He didn't introduce himself. Just smiled strangely but didn't speak to us at all.

We paid about 30 euro per night for the room, plus about a 20 euro "cleaning fee." This room is not worth that much for two nights. :-/ Basically 40 per person, per night. That was much too high for what we experienced. I have stayed in other Airbnb places that were either cheaper, or about the same price, that were far nicer (aka cleaner and more welcoming in terms of the atmosphere).

So, there is a the review! A number of positives. But also, a few significant negatives.
As mentioned, we liked Marco. He was welcoming and helpful. And the room was good. But there were some big negatives worth mentioning.

In terms of location, you are about a 7 minute tram ride from the city center. And roughly a 5 minute walk to the tram. This was pretty convenient, so we liked this.
