Upon arrival I was blown away by the view from the balcony- many a glass of wine were enjoyed out there. For the money this apartment is fantastic. Very well connected just a 1 minute walk from a big U-Bahn station (the public transport in Berlin is fantastic- the trains all run very very frequently and are not too pricey). The WiFi was a little unreliable during our stay and failed to work at all when on the balcony, unfortunately.
*Note: It is not mentioned in the instructions but when connecting to the WiFi for the first time there is an extra security feature which I only managed to work out after some experimentation. When connecting a new device to the router you have to hold down the WiFi button ON THE ROUTER for about 5-8 seconds. Then try to connect your device AFTER that. more
