We stayed of 8 days in this central, new and very clean set of apartments. They are very close the to the Plaza Mayor (3 minutes) and 10 minutes from the beach, so you can go for a morning swim and have breakfast at one of the many places in town, no trouble. The bus/train station is less than 10 minutes' stroll away for day trips to other places on the island (which is small enough to get anywhere and back in a day). We thought we might hire a car but didn't need to - not sure where you would park it in any case. All other tourist destinations in Palma (cathedral, central market, port et) are an easy walk. The room has great aircon and was cleaned every day, just like a hotel.
All in all, we were very happy and felt like we had made a very good choice. We would definitely recommend the Samaritana Suites if you are looking for an experience where you are very central, in serviced comfort but with the option to prepare some of your own meals.
