8 lads stayed in this apartment and it was more than ideal. Massive space that fit us all in easily. For the price you can't really moan. Had a bit of wear and tear, such as one shower head was broke and wasn't as powerful as the other one, but nothing major. We could be loud at times but had no complaints and couldn't hear anything from the hostel located below either.
Location for me was ideal, about 15/20 mins walk from the centre of Prague 1. This means you can find some gems on your way and experience the city a bit more. There is a couple of mini markets on the same street as well as a McDonald's and KFC around the corner.
Vaclav was great throughout the whole process, organised transport from the airport and was good at communicating throughout our stay.
Would recommend for a big group who are just need somewhere to get their head down and have a wash.
