Two key words: cleanliness and friendliness.
Naike is a really heplful and nice host. She gave us really good tips of which restaurants to go to, and provided us with every information we needed.
The flat is beautiful, and it was so clean! Very-very clean, which is really important to me.
The bathroom and kitchen were huge. The available moka pot,biscuits and tea were a really nice touch to the whole thing!
It is a 15 minute walk from the center which is okay. A bit tiring and the end of the day but okay.
Lastly, the train. It really goes past NEXT to the flat, so it is really loud and shakes the floor a bit. I managed to get really good sleep there, whilst my boyfriend kept waking up because of the noise. It really depends on the person.
Overall, we had a REALLY NICE exprerience. I would definitely recommend it, if you don't mind walking and you sleep well in a noisy environment.
