I had a pleasant stay at this apartment, being super close to the conference centre where I had to be (2 minute walk). For visiting the rest of the city I used Ubers (which are cheap for Dutch standards), electric scooters or the bus (all conveniently located).
One moment there was a large insect, I think a kind of cockroach. But I didn’t see it anymore, after that. Don’t see this as a sign that the apartment isn’t clean, because it was very well cleaned. I guess this just happens sometimes.
Thank you Rodrigo, for the efficient and kind contact that we had!
