Johan's appartment is exactly like the pictures he provided. Its interior is stylish, and the kitchen and bathroom are equipped with everything you need (coffee and tea, soap and shampoo). The bed is super soft, and we slept very well. The neighbourhood is peaceful and pretty quiet. The city centre is easily accessible by tram, and there's a supermarket within walking distance.
Johan is a great host, he responded very quickly to all our questions, and provided all the info we needed for the appartment, as well as for the city. He instantly made us feel welcome in his home.
To summarize: If you visit Rotterdam, we highly recommend checking out this appartment!
