This is a great place to stay. First of all, it is an awesome neighborhood and the building is beautiful. Despite the fact that it is a pretty old house the heating system is good and you will never fill cold there. At the same time, I have to mention that the heating battery in the main bedroom makes knocks from time to time, even during the night, so it can be annoying.
I also want to say, that the flat is much better then it may look like in pictures.
The table there, in a living room, can be expanded - which creates enough space for two workplaces and even for meals at the same time.
There are a lot of adaptors for European electrical plugs - so you don't need to care about it. There is also a printer there - which is super useful if you need to print tickets or boarding passes.
So, thanks to Richard - our stying in this flat was amazing!
