Location is great, and our stay was really comfortable. My and my siter stayed at to top floor appartment which consists of two bedrooms, both en-suite, a living room and a fully equiped kitchen. The hostess -and hubby- are really nice and welcoming. It's just a few steps from the Munthof metro st.; a short walk away from the Justice Palace, the rest of the city centre, the Parliament, restaurants and in a very safe neighbourhood.
I'd definitely recommend this Guesthouse to anyone who is planning to visit Brussels.
