Planning a solo visit to Luxembourg in September. Only been there once when I was 12 in the '60s. Interested in recommendations about:
--Moderate or inexpensive price hotel in Luxembourg city, especially (but not only) locally owned as opposed to chains. Wondering if there are regulations that prevent AirBnB-type rentals from becoming so numerous that neighborhoods are ruined for locals, because if so then I'd be open to recommendations of those kinds of rentals.
--Places to day-hike anywhere in the nation, especially wooded, any level of difficulty. Love places with cascading streams, gorges, etc. Not as interested in bucolic settings or village walks, unless you want to convince me!
--Any other not-to-be-missed suggestions nation-wide, including places to hear jazz or rock or folk, good restaurants, whatever.
Thanks!
