There is a very nice discussion which helped me on this issue (WFS and Bounding Box).
Defining bounding box within Add WFS Layer dialog of QGIS?
I quote from the other thread:
I started downloading the WFS content via the Add WFS Layer dialog and canceled the action. QGIS will add the layer anyway, with zero objects. In the properties menu for this layer I copied the getFeature address line, added the above mentioned &BBOX=.... extension, and went back to the Add WFS Layer menu. There I created a new WFS source and pasted the extended GetFeature command instead of the GetProperties address, hit the Add button and ... done.
Basically what he has done is do the usual:
- add WFS service layer
- cancel it on the run
- look to the properties of the newly created layer
- copy in the metadata TAB "Source of this layer" that huge link
In my case it looks like this:
GOVERMENTAL SITE HERE.tr/arcgis/services/TKG_KADASTRO/MapServer/WFSServer?VERSION=1.0.0&TYPENAME=TKG_KADASTRO:Parseller&SRSNAME=EPSG:3857&BBOX=3577366.30409,4712018.4004,3583224.9361,4707386.70703&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=TKG_KADASTRO:Adalar&SRSNAME=EPSG:3857
Add a bounding box extension to the end of the link like:
Hint: You can get the bounding box coordinates directly from Raster>Extraction>Clipper but be sure to add the commas in between.
In the end Add a NEW WFS layer with the bounding box extension and address combined.

You should be just getting that portion of the map. I find it helpful to save it to a different shapefile afterwards.
