My wife and I stayed in Jane's apartment for 5 days.
It is located on the second floor of a small apartment block, accessible by stairs. There is free parking on the street outside the apartment, but competition for spots near the apartment is fierce, so once we found the perfect spot, we just left the car there for the duration of our stay.
The apartment is in an older style apartment building and has been beautifully renovated. It was perfect for us, with all the amenities we needed - 5 minutes stroll to the beach, and a host of restaurants, bars, cafes etc all close by. It is located 3-4 kms from the centre of Barcelona.
Public transport (underground rail, bus) are all very close.
Jane and Javier were perfect hosts. Javier welcomed us and gave all of the information we needed to make our holiday in Barcelona a pleasure.
Minor problems were that traffic noise can be intrusive during busy times; and no soap is provided (which we found unusual).
In conclusion, we found the apartment to be excellent value for money, and we would recommend it to anyone wishing to visit Barcelona.
