The location of the apartment is great and pretty easy to find. The apartment itself is very cosy and clean, the bed was comfy. The wifi was fast and overall the stay was quite comfortable. The instructions and communication from Martins were clear and quick.
The apartment is located in part-basement and does have a bit of a musty smell mentioned in the other reviews. It seems that the smell is mainy coming from the original brick walls left uncovered, which, of course, look very cool. However might be worth considering doing something about it in the long run.
Some additional or alternative heating options could also be improved, as the strongest heater in the flat is an electric fan heater which in winter means having a constant background noise.
On a whole the flat is a pretty good deal for the price.
