I stayed a semester at Amber & Ruben and the first impressions were satisfactory, whether for the responsiveness on the booking, as my arrival.
It's not a big room, but everything is equipped properly and we have everything we need. Especially that the house is well maintained, clean.
The place is well located, close to shops, fast food etc. But also well served on transport.
The point that really bothered me on the other hand, concerns the three puppies of the house. From 6:15 am, they are already starting to make noise until the end of the day. What makes that one awakes inevitably early and that one can quickly be irritated in the long run.
