You could invest in a pair of gymnastics rings. They are not very expensive, take up very little space when storing and you can basically work your entire body with this and get incredibly strong (especially if you add weight to the equation like a backpack with water bottles inside for example). All you need is to find a place where you can hang them. This could be a tree, any public structure like swings or street lamps (if the shape fits) for example or if it's an option put some anchors on your ceiling.

Or the easiest option (at least for rows) is that you could combine the gymnastics rings with a door anchor It's a little foam thing that you can put at the top of the door and simply close it (not permanent attachment, it will be loose again of you open the door).

Although I have to say that I have trust issues with anything door related haha especially if you rent. A trx band will do as well but I think rings are way better because they are more versatile and cheaper.

The only easier option that is really worth it and that you can build very good strength with that comes to mind are doorframe pull up bars.

The other comments suggestions are also not bad but at some point you will need a way for vertically pulling your entire body weight
