Sarah gave us detailed directions to the flat and where to park etc. She met us downstairs and showed us up and around the flat (with Casper the puppy in tow :) ). The bedroom is perfect - cosy, beautiful and quiet - while the rest of the flat is bright and airy: we were encouraged to treat the kitchen and living room as our own. We were made to feel like guest members of family - the girls are very friendly and relaxed around visitors, and we ate with them at breakfast on the second and third mornings (including the youngest's birthday, when we were treated to pancakes). Sarah went to every length to make us comfortable, and even bought some soya milk for me when I mentioned that I couldn't have dairy.
Our only hiccup was a slight panic when we couldn't get hold of Sarah for a couple of days prior to arrival to get the house number. It all worked out fine in the end, so please don't let this be a reason not to visit such an amazing family, just be aware that replies might take a few days to get back to you.
