Truly a fantastic place to stay in Brussels and great value! The apartment is beautiful, clean, cleverly decorated, spacious and in a very nice neighborhood with easy access to restaurants, shops and the metro. Alin has gone to lengths to make the experience as friendly and easy as possible for his guests, including an incredibly quick and easy check in/check out process, daily maid service, detailed instructions, and apartment amenities well laid out with labels all over the place to keep things tidy when multiple parties are staying there at the same time.
It is definitely NOT the place to bring a handful of drunk partiers back to (that's what hostels are for). Please respect the other guests and the hard work Alin puts in to keep the place clean.
Only one very minor downside: if you are looking to party into the wee hours in the city center, the metro line from the central station to the stop near Alin's place shuts down before some of the more central lines so you may need to get a taxi. It's a 10-15 minute ride and costs about 15 euros.
All in all, I would highly recommend Alin's place to all travelers except those that are looking to party late at their accommodation.
