The apartment was stylish, clean, great beds, large kitchen (though dishwasher didn't work), two great bathrooms and showers, good location (tram in front of the house), neighborhood with plenty of shops, restaurants and bars. Convenient for three couples.
The apartment is rented/maintained by a company that owns many apartments in Brussels. We've been emailed by 4 different persons, so it's not very personal, (the woman who welcomed us was person nr. 5). The company demands a € 1500 deposit. The apartment is on the 4th floor, you can climb the stairs (100 steps) or take the very small (max 3 persons) and somewhat rickety elevator. Inconvenient: only one pair of keys (for three couples). Bit disappointing: not a single Christmas decoration and very general tourist information.
