My husband and I stayed at Happy Guesthouse over a long weekend in celebration of my birthday. It was our first time together in the city and we felt like we hit the jackpot with this place.
It's in a great location just a few mins walk to Grand Place and city centre but also it's just nestled right near the lovely area of Sablon. There are only a handful of rooms with one suite on each level of the guesthouse (so if you can't climb stairs, it's probably not a great option for you). The staff is incredibly attentive, flexible and willing to help. We adored the breakfast every morning in the bright and open sitting area with some homemade, local treats as well as standard European breakfast staples.
The room itself (we were on the top floor) was spectacular. A large, comfy bed, a desk a dressing area and a modest but well laid out bathroom made it a great spot. The roof is pitched but there was a skylight that was great for seeing a view of the area as well a small terrace for reading or catching some fresh air.
Overall we loved this spot, wouldn't hesitate to come back and recommend it to anyone looking for a comfortable and cozy stay in the centre city of Brussels!
