Really great place with lovely hosts who were close by and responsive to any needs that arose, but not so close that it felt like we were staying in their house or similar. Great setup.
The flat was located in a really nice quiet area with a very short walk to various interesting locations, shops, attractions, etc... There were recommendations given for things to do/see/eat and it was so well located that exploration felt effortless and comfortable.
The flat itself I would say the pictures do not do it justice. It is spacious, comfortable and warm with a good amount of character. Can't fault it at all. It's really nice to have a proper shower setup as it can be a bit of an afterthought in many Airbnb's.
Overall we highly recommend this accommodation and Rotterdam as a place to visit!
