hjælp til rettelse af engelsk oversættelse

I have a friend who is going to London for six months. She wrote to a bureau, whose(tror det skal være which men er ikke sikker) speciality is private homes to people who are looking for accommodation in London for a short time.
In the letter which she received from the bureau, it said that the cheapest solution probably would be a bed-sitter, which could be obtained with or without kitchenette and bath. She could also – which might be preferable in her situation – choose a flat on a sharing basis.
Last winter, when her parents were in London for three weeks they contacted another bureau, with whom you can rent a furnished flat, which has almost the same service and facilities as a hotel, but where there is more room and a better opportunity for privacy.
The reason why they picked this solution is that her mother is sick and tired of hotels, which you can understand in view of the fact that her job involves a lot of business trips. The stay was a huge success, and they will make their arrangements in the same way, whenever they have the opportunity to do so.

jeg kan ikk rigtig se andre fejl. Altså er det noget du har skrevet eller som du skal finde fejl i?
