My family really enjoyed their stay at John and Hayley's.
The apartment is really nice, tidy and clean with a lovely décor. It's also located in a really nice building with a friendly porter, which feels really secure.
John and Hayley have both been extremely helpful and kind, replying to my requests really quickly, even within an hour! They also provide a detailed house manual with useful tips to what to do in the area, which I though was really nice.
I strongly recommend their apartment.
