Two bathrooms, 2 toilets, 1 big room upstairs and 2 smaller rooms downstairs. A huge living room and big kitchen. Just 2 min from subway and 8 min by public transport to center. Great for bigger groups and families. Its a flat where I live! So my stuff is there, my friends sometimes. And me :) Not always, depends on my work and other activities. Just ask.
Oh, there is a balcony also... you may even jump on the roof and have a morning coffee with a view on Prague :)
