Valentina's house is perfectly located. Close to the shops and a short walk to the beach. The room (another room than shown on the photo when booked) is perfect. Especially the fact that you have your own bathroom. I had the living room/kitchen to myself. Even though I didn't really use it, it is really nice (everything is new and clean). In general I have just 2 minor things about my stay that could be better, there is a window in the room that has no curtains, so If you are a light sleeper like me, the light will wake you up around 6.15 AM. For me this was no problem, because I didn't go out and didn't need to sleep in. But otherwise this might be bothering. Another thing is that the place is missing WiFi. It is really annoying as a traveller to not have wifi. All the nice cafés and bars in Byron don't have WiFi, so you're stuck to the tourist/backpacker places for that. Other than that it's a perfect place.
Oh and if you want to relax one night, at the end of Gordon street there is a nice cinema (at the Brewery), showing Arthouse films.
