The apartment is very new, very clean and beautifully situated with an interesting view of the marina by Fornells harbour. The beds were comfy and the kitchen well-equipped. Valenti was brilliant at helping us book a taxi (do note, the taxi service is appalling on the island - they never answer the phone so booking was very hard, and they only arrive at the taxi rank sporadically). Check in was straightforward.
Fornells itself is beautiful with a lovely range of restaurants, a decent supermarket, and a children's playground. There are some swimming areas, but if you're looking for a good beach for children Arenal d'en Castel is much more suitable (stunningly clear water, gentle slopes, and sun loungers to hire). The bus there is roughly only every half hour though (times are on the internet). We did try Platja de Fornells too but didn't like it nearly as much. We'd really recommend both Fornells and the apartment.
