I would stay at Lieke's place again. It's bare bones with little charm (walls are bare and niceties are rare), but it's clean and functional. Balcony does exist but you have to crawl out the window to get to it. Very close grocery stores and coffee shops are a big plus. Close RAI convention center and Tram #4 station are welcome for conference attendees. Only surprise was the existence of a few mosquitoes in the apartment (in October!) during my first few days. One bit me but I killed it. Since windows and doors remained shut, it was hard to know how they got in but they weren't a problem after the first few days. Bathroom spaces are fine. Rense checked me in. He was kind and helpful with restaurant tips.
