We had a wonderful stay in John and Frank's apartment. Communicating with Frank in advance of check-in was so easy and he was incredibly helpful in giving us tips on what to do and where to go in Palma. We were even able to drop our bags before checking in properly after arriving on an early ferry, which was much appreciated.
The apartment is large and immaculately clean, with a lovely balcony overlooking the square below. The neighbourhood is a short walk from the sea, the cathedral and the main centre of the old town, but it is so quiet at night so no problems with sleeping. There is a lot of fridge space, great cooking facilities and a big selection of books to peruse. I would definitely recommend if you are coming to Palma.
