Rudy's place is reasonably located, very close to a tram stop and subway stations. In walking distance is the metro station, a mall (with Albert supermarket) and many restaurants. There's also a small convenience/liquor store very close by for small purchases.
We booked at short notice and Rudy not only kindly accepted us, but also let us extend a night! Very good communication. Checkin was smooth, as his friend was waiting outside for us exactly on time.
The room is actually like a private studio and has a small kitchen and bathroom. For the price it is very good value, however as it is downstairs it is a little stuffy (solved by opening the windows for a few hours each day). The bathroom is very clean, however as it is old the plumbing can get a bit smelly and the shower doors are fiddly to use. Water does build up in the shower but we have found this is the case in many, many places (even the expensive ones) so it was no surprise.
Kitchen has everything you would need but is very small, so would not recommend cooking extravagant meals. Fine for cooking a fried egg or cereal :)
The wifi was OK, but not very high speed.
Overall would recommend for the budget traveler for a place to sleep and shower, but not if you plan to stay inside a lot.
