I stayed at René's place on a family trip with 4 other adults and it was very spacious with plenty of communal areas with 3 separate bedrooms. We never met René but were greeted by Hannah who was quick to respond to any queries we had and there was a welcome booklet with house rules as well as some detailed recommendations for food and sightseeing. The location is very central with most of the tourist attractions within a 20 minute walk but there's also a subway station at the end of the road for those who aren't as mobile. All in all, it was a very clean and comfortable apartment to stay in, perfectly located for a tourist visit, I would definitely recommend to other travellers. If you do go, make sure to try out Veganista, the vegan ice cream shop across the road, especially on a hot day!
