I didn't have the chance to meet Ruben in person as I was out sightseeing as much as I could fit during my two day visit but he was a very friendly and accommodating host, giving me the code for the apartment and allowing me to come by before normal check-in time to drop off my luggage. The room and shared space were kept spotlessly clean and it was a very comfortable stay. I would gladly stay here again on my next visit to Amsterdam!
