Was in the Sala Montana lounge (B gates, non-Schengen) yesterday. I agree that it's a very pleasant lounge with a good selection of pastries, sandwiches, coffee etc at breakfast time. Plenty of seating and good wifi.

The only issue that I had, having just come of a TATL flight, was that whilst there are showers advertised, these come at an additional cost - €16 IIRC.
