I live in a neighborhood of Katowice together with a very well integrated Romani diaspora. They dress their way and speak their language among themselves, but otherwise are regular members of the local community. Their kids go to local schools and I often see mixed groups of children playing together. I also occasionally see mixed couples openly displaying affection, which is something I would be surprised to see just a few years ago. The tenement houses they occupy stand out, being very well maintained and clean. It's obvious they are putting a lot of effort into being perceived positively.

To offer some counterbalance, a few years back, on the outskirts of nearby Wrocław, a group of nomadic Roma elected a slum like encampment (you can see how it looked like in this trailer of a documentary about a deaf Roma girl passionate about Bollywood). AFAIK the slum was demolished since then. These guys were much more like those seen in OP's video.

In the end it really depends on which group of Roma you encounter. Here in Poland we have a very well integrated diaspora, with its members often becoming participants in Polish culture, but for the most part essentially invisible. After the fall of communism, however, different Roma immigrated from the southern part of the continent. Nowadays you can encounter both groups, with the integrated kind getting considerably less exposure, thus the nomadic, poorly integrated kind having much more power in shaping public perception of the entire ethnic group.
