The apartment is functional and spacious. It is effectively a large open plan room, with a separate bathroom/toilet. It was difficult to get up early in the morning, without waking the rest of the family. Central heating runs ok, the small kitchen was suitable for tea, coffee and food reheat, we did not test it for more. The fridge works and is large.
Shower was a bit of a challenge, as hot water kicks in and out at times.
Lack of lift (5th floor apartment) and wifi - we knew about it beforehand and managed to survive.
Overall our stay in Peter's apartment was a good experience.
