The guesthouse is about a 1-minute walk from the Brunnenstraße bus stop and about a 2-minute walk from the pedestrian zone.
Requests are usually processed promptly.
Sometimes it's possible to have breakfast (including drinks) at the Pyrmonter Hof (same owner) for €11. You can also pack your dinner there.
The rooms are equipped with a stove, sink, and microwave. A TV is also available.
In short, this is a great place to stay, even for a longer stay.
