This airbnb experience was one of the best I have ever had. The apartment is gorgeous (bigger than I expected!), the wifi is quick and bathroom is beautiful. It's very easy to get to on the tram (just over the Erasmus bridge from the ventral part of the city). I added an extra friend last minute, and it was not a problem. We also needed a later check out time (we were running the Rotterdam marathon and wanted to be able to shower/store our bags during the race, but had a late flight that day) and Nathalie made it happen. Although there were other renters in this apartment after us, Nathalie has a second apartment above this one she let us use, after also moving our bags there during the day while we were racing. She definitely went above and beyond to make our stay incredible. Thank you so much!
