This is definitely a hotel to consider if, like me, a quiet and relaxing hotel is your top priority when you visit Bonn.
The Avendi is one of two modern Seminaris conference-focused hotels situated in a parkland environment in the middle of Bad Honnef. So many rooms face onto a large grassy courtyard, rather than a street.
Staff are efficient and friendly. There is an excellent restaurant. Shops and restaurants in Bad Honnef are just a few minutes walk away.
The rooms are large, modern and well appointed. Complimentary internet connections in rooms are wired, but there is a WiFi hotspot in a small library with tables.
A health, fitness and spa therapy building is joined to the hotel, with a large indoor swimming pool.
Bad Honnef is at the end of one of the U-Bahn lines - journey time to Bonn Hauptbahnhof about 40 minutes. Bad Honnef also has its own mainline railway station which is directly connected to the station at Cologne-Bonn Airport.
To get from the mainline railway station you need a taxi, but the U-Bahn station is a pleasant 10 minute walk through the park and then quiet streets.
You don't get a free U-Bahn tourist card as you do in more central Bonn hotels, but the additional cost of a day ticket is not much.
Overall, therefore, a very enjoyable stay. This is a 4 star hotel without reservation, good value for money in the Bonn area, and I'll stay here again.
