Me and my friend stayed for 12 days in Hermine's House in the room with the 2 single beds and a desk.
We had to work while there and the little desk worked super well for us.
The house was super clean and the location perfect as we could easily go either centrally or towards north-east to visit friends.
We knew our way around the city pretty well but the house should be perfect even for newcomers without spending a fortune. It has numerous buses taking you centrally as well as the overground station only 2 mins walk away.
Hermine is super friendly and easy going and we will definitely be staying with her again in the future.
