Hester's place is even better in person than on the pictures. It's cosy, all the decor elements make you feel right at home, and all the equipment works perfectly (wifi, shower, kitchen - which includes great amenities, etc.) It's very roomy for two people and the light pouring in is beautiful. The bed is comfy, the sofa as well. It makes a nice place to come back to after a long day of exploring Rotterdam.
The location of the apartment is also super nice: right next to nice brunch places (Arzu, notably), a cool-hipstery sunday market, and a tram stop (lines 7 & 4) that takes you right in the center of the city which has so much to offer.
We recommend Hester's place warmly and cannot wait to come back!
