Me and my girlfriend spent 9 lovely days in the apartment with Isburg and his partner; two people really kind, nice an easy to talk to. We always had our own privacy in the room and they shared with us their kitchen so we didn't have to pay to eat out often.
As mentioned in other reviews, the room face a small garden with roosters and the building is close to the airports. But we never had a problem with the noises or the lights (no shutters in the room). The main problem for us was the hot, becuase the humidity there was really high and there's no Air conditioning in the room and house. However, Isburg provided us with a fan and a little fridge in the room (very useful to store and cool bottles of water). Despite the hot, the apartment is at the last floor of the building so during the night is usually windy and pleasant (if you sleep with the door of the room a bit open, the window open and the fan should not be a problem) but from 14 to 16 is really hot in the room. This can be said also for the bathroom. There's no window to the otuside (there's a window that open to the interior of the house with the pipes for the water but it's still hot) so if you go there during the hottest hour of the day is like a sauna (we bought a portable fan to bear the temperature). Again, the bathroom is clean, stored but maybe just a little bit small, especially the toilet but this shouldn't be a huge problem if you don't spend so much time in it (of course is not their fault, the bathroom is what it is).
The only "problem" we had was that sometimes the kitchen was not left completely in order with pots and pans with leftovers still inside for much of the day, and the overall mess inthe kitchen (that would explain the 3 stars I gave in cleaning). I am not here to judge becuase for us it has never been a problem becuase we are people that adapt easily (and there was always another pot or pan available to use), but i can undertand if someone else complains about it.
Overall the experience was lovely and great. If i can give a suggestion itrrecommedn to do less days than us (i think 9 are too many). Probaly the staying wold be even more great if you spent max 3/4 days. But isburg was really kind and offered us to wash the bedsheets and all of our clothes becuase for them it was their first experience with people for so long.
For that price, in Palma (5 minutes to the beach with really clean water, and 30 minutes of bus to the centre) i think you cannot find anything else. It is a bargain. Isburg and Alexander are kind, easy going and make you feel like you are at home. They don't have a problem to share anything. Even the last two days, when me and my girlfriend didn't feel well and had to stay in the apartment, Isburg and Alexander were super nice and tried to help us as much as they could.
I really recommend the staying.
