Alright, went to check out the place. It's pretty perfect! Cheap, close to the center, close to MRT (same line like Computex venue - about 15 minutes commute!). It's actually just one floor of an appartment building that we'd be renting. At the moment, there is room for 7 people: 3x double bed, 1x single bed. If needed the owner can add another matress to fit two more people. There's a table, micro-wave, showers in every room and a small living room area too. The total cost to rent the place from June 1st till June 14 (two weeks) is ~ $60k NTD, which is about $4300 NTD a day or €108 / $146 USD. Per person, that comes down to:
1 person: €108 or $146
2 people: €54 or $73
3 people: €36 or $49
4 people: €27 or $37
5 people: €22 or $30
6 people: €18 or $25
7 people: €16 or $21
Now, I managed to get an option to rent that expires on Friday because it would be rented out not just during computex, but also the week after. They also asked me to put a down-payment of 50%, which is not a problem. Since the place is pretty damn cheap for the location, I'm willing to take it if there's at least three people confirm to stay there. So, if you want to get stay in this appartment, please post in this thread AS SOON AS POSSIBLE!
