I have stayed at the property for 31 days. I am not recommending it for a long term. 1-3 days is OK, more days could cause issues with a lot of things such as flatmates, often dirty dishes in the kitchen, bathroom issues, even toilets.
The cleaner Agata is one of the best person that I met in London. Hard worker, kind and active same as Roland - plumber.
Ben, the manager of the property is not that good as I expected during living in the property. You can find his ignorance on the first place. Carrying about his profits is more important than taking care of customers. I don't believe this will change.
Hope Agáta and Roland will find a better job than this. They deserve it. And Ben? He can start do cleaning and plumbing services to learn what is needed for the properties.
Peace.
