A lovely, spacious apartment above Aaron's home near the small town of Portal. We (me, husband and 20-month-old son) had a great one-week stay at the house and felt at home. Aaron is available to answer questions and help with anything you need, but if you don't need anything, you'll barely know he's there. His place is on the ground floor and the apartment is above, with a completely separate entrance. The pool area is lovely, though we stayed mid-November so couldn't really make use of it. The dogs are great fun - our son loved playing fetch with Tokyo (and Tokyo really does LOVE playing fetch) and there's a goose and three chickens for extra animal fun.
The grounds are huge and very private, with an app-activated private gate shared by, I think, one other family who live next door. There's lots of balcony space too if you prefer to just use that. Note that there is a smaller ground floor flat that Aaron also rents out, so the shared space won't be exclusively yours. It's plenty big enough for two groups to share, but bear in mind if you want complete privacy.
One thing I don't remember reading about when I booked is that the kitchen sink isn't actually in the kitchen, it's outside on the balcony with a dishwasher. So when you want to fill the kettle or rinse your hands when cooking, you'll need to go outside onto the balcony to do so (the sink and dishwasher are under shelter but it rained quite a lot when we were there so things did get wet). We got used to it and it wasn't a huge deal, but when the weather isn't nice, it's not ideal. If you're there to do lots of cooking then this might annoy you.
Aaron converted what is often the third bedroom (just off the living area) into a kind of sofa/lounge area, which was great because the floor to ceiling windows provide amazing views out towards the airport and fields (nicer than I made it sound). Incidentally, the airport is super close by cab (20 mins) but doesn't feel close like it would if you were 20 mins from Heathrow, for example. It's not noisy.
Portal is about a 20 min walk away (with a hill), and in the town there are all the usual things you'd expect: small supermarket, bakery, places to get coffee, lunch, etc. There's also a small play area, which our son enjoyed. We used public transport to get into Palma, which is excellent. The bus stop is about 10/15 mins from the house, and you can pay by contactless, then get off at Marratxi for regular trains all over the island (if you're with a kid like we were, the buses have rear-access for prams, and off season were pretty quiet, so a nice way to travel).
