Kai's place was an absolute gem to stay at and the description does not do it justice. Hopefully I can add some useful information.
1) The location just outside Capdepera is quiet and rural, there are houses either side of the large plot but the high hedges ensure complete privacy. It's a 5 minute car drive into the town which has several good value restaurants. It is possible to walk there but it would be alongside a main road so not very nice. There are excellent beaches just 10 minutes drive away, the best being Cala Agulla with it's large car park, clear water and lovely sand. If quieter beaches are your thing then the beaches north of Cala Mesquida are ideal but mean a 15 minute walk or taking the car down a very rough track.
2) The house sits on a long, private plot and is very well equipped and spacious inside. A previous reviewer mentioned WiFi and a dishwasher - these are not provided although the mobile phone signal is 4g and good strength. The TV only receives German channels. The terrace at the front has a range of seating and choice of sun and shade to keep everyone happy. The little pool (2m across) is ideal for a quick dip to cool off but older children would probably be a bit bored with it.
3) The check in procedure is very DIY with the owner posting us the keys a few days before we set off. Clear instructions were sent to us as well with good communication over WhatsApp. This suited us but if you are more used to been given a tour of the property on arrival then it might not be for you.
Would we go back again - Yes!
