Nice flat (especially loved the design) in a great location. In addition Victoria is a very friendly and helpful host, it was a pleasure to talk to her and it was easy to ask for any help.
The only thing I wasn't really happy with — the mattress felt very uncomfortable. If you have any problems with your back it can ruin your entire stay in the flat. Especially if you plan to live here for a few weeks, as was in my case.
It can also sometimes be quite noisy due to the fact that the flat is located on the lowest floor and near the entrance to the building.
Otherwise, all was fine. I think for a short stay it's a nice option.
