Ethel's place is great for a short term stay as the room is cosy and comfortable. A longer stay is a bit more difficult just because of cooking reasons but it's very clear what you get in the description.
The place is very modern and very clean -- heated as well which was great in the autumn months !
The room is very private as well with your own entrance so you don't have access to the rest of the house and go out via a patio/garden door.
The location is fantastic. About 5 mins walk to the Spaklerweg metro station and doesn't take long to get into the centre/touristy areas.
Would highly recommend.
