I recently booked my stay here for 1 1/2 weeks. I was in the area for a class and asked everyone about their hotels - I was originally staying at another hotel in Kaiserslautern but quickly that it was not so great. The Air Royal has huge rooms; I stayed in a single room on the top floor and had a huge room. Instead of being a hotel room, it felt like a large studio since I had my own sitting/dining area. Everything was emmaculate, clean and the design was crisp and modern. I think in this area, it's a hard find and after asking around, most people were in very small rooms with outdated furniture, no ventilation and crappy service. The Air Royal is the total opposite. All the staff was so accommodating (even received a goody bag at check out for my trip to the airport).
The room has great ventilation in the bathrooms, which is hard to find in this area, free wired internet, easy parking, comfortable beds, fantastic breakfast with tons of fresh fruit, and is in a great area in Landstuhl. The hotel is 10 minutes to Kaiserslautern and 5 minutes to Ramstein.
You can't beat this hotel...and it was more reasonably priced than the crappy rooms I found elsewhere!
