Erik is a very kind and helpful host. He is very fast in responding our mails.
The check-in was easy and Erik has also a few tips for you how to explore Rotterdam.
There is everything you need in the apartment, there are also bikes you can use if you want. Unfortunately I have to note that the air in the room was kind of muggy. For a few days the room is perfect.
The location of the apartment is also very good. You can reach the center by tram or walking in a few minutes. Nice neighborhood with international shops and bars.
