Everything went great. The two hosts were friendly and reliable. The flats are as pictured. The flats are very bright. One bathroom (of two) is outside. If you know each other and live in everything together, it's great. The bedrooms are very dark as there is little light. Everything is clean and 100% vintage. (not retro fake, but original) The highway is always present when the windows are open and in the garden. We were allowed to experience 2 parties. They were well organised and relaxed. The next day everything was cleaned up and put away.
The kitchens are too small for 12 people and could be a bit better equipped. We always sat outside with 9 people. That went quite well. Basically, it gets quite tight with 12 people for the 2 flats. We were 5 children and 4 adults. That was okay. We felt comfortable in these winding garden levels and can only recommend the BaBarum - for all those who like it colourful, retro and friendly.
