We had a very nice stay in Eider's flat. The flat was welcoming and we used the terrace every day.
There is a gym downstairs with many weights and equipment (treadmill, elliptical, rowing...)
Access to the city is SUPER easy as the bus stop is literally in front of the building and there are 3 lines that takes you to various part of the city centre. After 11pm, you can just call a taxi and they all know where "Miramon" is.
Although there is a parking, we rented a car for a couple of days and left it in the street overnight, there is plenty of space to park.
