One thing you should know, is that the house is exactly as it is shown on the pictures! Stayed there with 3 other friends last week, and when we arrived we were amazed with the view of the sea and the house in general. It is clean, it offers you all the basics and even more, and with a really nice location (bus station, supermarket, bike rentals, etc around the corner). Beach also is right across the street. Javi is really helpful and he offered us some info on what we should do in Mallorca. He was also available for us if we needed anything.
In case you want to be somewhere close to the center of Palma this is not the place, it took us 30 mins with the bus to go everyday. Also, it does not have an air conditioning which was a bit difficult with all the humidity we faced the days we were there. The fans though helped the situation.
Definitely recommend it!
