Stayed in Villa Russadir in early-August 2017 (the hottest week imaginable...temps hit 38-40 each day!)
Bottom line: Great location, nice property, a couple of misses.
Property: The Villa has an excellent location, just 2 blocks from the restaurant/shopping downtown area of Cala D'Or. While we didn't go to the beach in this town, it was similarly close. The pool out front (pictured) is very beautiful, though there's not a lot of room around the pool. The interior of the property is relatively simple, though there are plenty of bedrooms for a large family, and good space for kids. The kitchen was a bit problematic, with a poorly-designed stove, but the washer and dishwasher were fine.
Service: Here's where things broke down. The Villa comes with a comically long instruction manual (15 pages I think?) that's very detailed about small meaningless stuff, and, because of its length, means you miss the important stuff. There was miscommunication with the staff about parking, in which the staff contradicted the instruction manual, resulting in a E80 parking ticket. Ouch. There is parking in the Villa driveway, but one must request that in advance, and the space is very narrow--only ~15cm wider than our rental car.
On the plus side, the property managers did have 2 cribs, and also provided us with beach and pool toys for our young kids. That was a nice touch, but make sure to ask for them in advance.
We had a great stay at Villa Russadir (4 adults and 2 young children). It is very well equipped and centrally located. 5 minutes walk from the Marina (surrounded by great restaurants) and 5 minutes walk from the town and beach, which is lovely. The pool is beautiful and there is a great veranda to sit out on. There is a BBQ which we enjoyed making use of. We chose not to hire a car and didn't really need one.
Jesus was a pleasure to deal with and was on hand at all times to answer our queries via phone and what's app. Jose was also there to look after the villa and was very helpful and accomodating (he kindly drove us in his van to do our shopping!).
Would definitely recommend this villa and would have no hesitation going back.
