We had a very wonderful stay at Rob and Feng's which are very friendly and welcoming hosts.
The emplacement is very nice and quiet, in a pretty little street next to the center with a really close metro station (Only 4 stations to the central station)
The room is decorated with a lot of taste and very comfortable.
Rob and Fang gave us a lot of good advices in order to visit the city in 2 days, great address to test in the area and in all the city.
We highly recommends Amstel Nest and won't hesitate to come back !
