I visited Brussels when the annual seafood conference took place, which resulted in accomodation costing 350 - 550 euros per night. As cost concious traveller I looked for alternatives and found Leuven and the brand new Park Inn adjoining the railway station.
The journey from the airport takes approximately 15 minutes and it really is a walking distance to the hotel. The hotel is very modern, so I agree it lacks the medevial charm of Leuven, but in my opinion the suberb location cures this little deficit.
The old centre of Leuven is a short walking distance away. Leuven as a university town with a large student population offering a good selection of very affordable restaurants and bars. More expensive (and presumably higher quality) restaurants also exist. The town itself is quite easy to navigate and very idyllic - there also is good signposting to all central sights.
As a tier loyalty programme member I got a very nice corner room, which was all new. I was told that the hotel opened only in November 2011. I slept like a baby, no noises or voices from the corridor or the adjoining room.
Staff was friendly and attentative. Some waiting at check-in and check-out, but you need to remember this is a three star property and not four or five. The breakfast buffet is OK, not as comprehensive as at its rich cousins (Radissons), but perfectly acceptable. Hot meals were also available.
My room had a separate toilet (without wash basin) and shower with wash basin. Not the most usual design, but quite pleasent and functional despite the small floor area used.
Overall, a very pleasent surprise and good value for the room rate I paid (180 euros breakfast included). If you visit Brussels often and know the central Brussels too well, I warmly recommend to venture out to Brussels. Trains to central Brussels are very frequent and the journey takes approximately 30 minutes. I took a 8:27 am train to Brussels Centraal and there was a lot of room for luggage and even got a seat, so no reason to worry about travelling with luggage in the rush hour.
