Hi Juniper
I have only been on this trip 6 times. However its been a couple of years now since my last stint. I think the Town of Altenahr is a fabulous little town. The scenery when you are out walking is fantastic, Especially on a nice day. There is a lovely little castle opposite the hotel which looks lovely when lite up at night. And take only about 15 minutes to walk to. However it is all upwards. But the views are magnificient.
There are plenty of eating places only a few yards from your base. And if you like a little cake with your coffee or some ice cream. There is a nice little premises right across the road, Which I highly recommend.
You will enjoy it. I am sure your only complaint perhpas is that the trip was not long enough.
Have a great time and enjoy
Andy
