Our room was huge with two beds and although it was hot the fan was good at keeping the temperature appropriate. The whole place was very clean and comfortable - like a home away from home. We had bicycles that we could store on the balcony off the kitchen - just a short climb from the entrance. It seemed very quiet when we were there although all rooms were full - I guess we were all on different schedules.
It is very well organized with self check-in and instructions for everything. We never did meet "Tim" or anyone else responsible for the Guesthouse. Some people may find this a bit off-putting but it was great for us and it all worked. ( much better than checking-in behind those with numerous questions - dumb or not).
The location is great, close to the station, the trams and with many restaurants etc close by; they supply lots of maps and suggestions for places to go. We got more great information here than places we have stayed where we had personal attention!
And for Portland the price was very, very reasonable.
