Chose Wiechmann through website as it looked charming and not too pricey. The buildings were indeed charming and the location was excellent. Taking the ample breakfast overlooking the canal was a delight. On the downside, we struggled with the stairs somewhat (incredibly steep and narrow) but I guess that's a feature of these houses and not much to be done about it. We were on the top floor so it was a long haul with our bags. It also meant our room was incredibly hot - we had the windows open the whole time and the fan going a lot of the time. It would have been nice to have a view of the canal, but at least being on the top floor we could look over the roof (and into the neighbours' kitchens!) instead of at another wall. Also disappointed to find that our room, booked as a double, was actually twin-bedded. Mattresses very soft.
The bathroom was clean, shower worked perfectly, as did the tv.
The lounge was comfortable and my partner loved the resident dog!
I would stay again if we could have an actual double room, with a canal view.
