I seen Erika 3 / 4 times or so. Couple years back. Same flat. Same problems with noise / walls.
At the time she was a reliable , good , clean punt. As she appears to be now.
For me , she just didn't "float my boat". Not great OWO , more hand than mouth. Closed her eyes whilst fucking. Turned her head away. Just didn't seem to be fully into it. Not been tempted to return.
However , ( apart from the neighbours / noise thing ) , great flat , good location , clean girl and good hostess. Just not in my own personal top 5 , maybe top 10.
Just my opinion.
