I must have stayed here at least about 5-6 times from 2003 to 2007, some of my stays were for a month or more. My recent visit here was on 16/11/2013 and myself and my friend traveled to Bad Homburg just for a day to meet some friends and just re-live memories of this place.
Hotel Arkadia was the obvious choice. We booked a maisonette and the room was very good. Earlier I had always stayed in a Single bed room. The hotel is comfortable and very good. Am Houiler Platz has a few shops nearby, there are two Chinese restaurants close by, Kim Kim and Me King. S – Bahn station is about 5 minutes by walk and very convenient to get to the city.
Overall it is a very nice place to stay. Internet can be a problem. You have to purchase it and for those who just want to update facebook status on your mobile, it doesnt make sense to spend 15EUR for that. You are better off with your mobile data connection.
Otherwise it is a very nice place to stay. I would definitely recommend this place.
