We stayed with 4 friends in the appartment, the appartment is big enough four 4, 5 would be little too crowded. The appartment is on the 5th floor, but there is an elevator. There are 2 bedrooms, the room with the double bed is smaller than the other room. The double bed can be a little small if you re not a couple ;) (I would guess about 1,20-1,30m width). There is a big closet where you can put your stuff in and has plenty of towels and extra blankets and sheets.
The bathroom is quite large with a luxury shower. There is enough warm water for everyone to take showers after each other.
The living room contains a relaxing couch with an tv recorder, you can watch movies on it, the music channel is nr. 103/104 if I remember correctly.
The kitchen contains a dish washer and enough stuff to be able to prepare dinner. There is an oven, microwave, frying pan, cooking pans, water cooker, breadtoaster, big fridge, freezer and blender.
The location is great, a lot is walking distance from the appartment, bars, restaurants, supermarkets, metro, parks etc.. We really enjoyed our stay, the host of the appartment is perfectly reachable through whatsapp for suggestions about restaurants, bars, taxi etc.. And last but not least the appartment is superclean!
