We stayed for six nights. The place is nice and comfy in a very quiet neighborhood so we had great nights of sleep. Just keep in mind that you are in the basement so you will hear noises upstairs but it didn't bother us.
The train station is about 12-15 min walk. We came back late every evening but had no issue along the way.
Breakfast is nice. Plenty of fruits for a healthy morning.
It takes about 35-50 min into the city depending on where you want to go.
