The flat is pretty but very small (the pictures make it seem bigger), we got a one time reduced price - I personally would not book it for the regular price. Matt was very helpful and welcoming before, during and after our stay and would help With every problem that would arise. Unfortunately there were quite some, be mostly they could be solved easily.
Generally things were okay, almost everything was cleaned well (except for the fridge)
I would definitely only recommend it for a short stay AND if you do not plan to spend a lot of time in the flat. Definitely not suitable for staying in the flat for a long time or to work. It is quite loud at times (and not suitable for online meetings at those times or for concentrating well). The internet worked well, but had to be restarted some times because it would stop working in between, ect.
For me there are only 2 things that really were irritating: the lid of toilet would rest on your back when sitting on the toilet (this is because everything is so small that the toilet doesn't properly fit into the room). There were no ventilators - neither in the bathroom (toilet + shower was in one very small bathroom) nor in the kitchen wich resulted in bad and persistent smells.
