Elvira's place is located in a beautiful and very safe part of the city. Transportation to all the significant attractions are right at the doorstep.
It is also a great walking location. The Gracias neighborhood and Park Guell are easy walking distance.
The room is quite nice, with lots of closet space and it is also very quiet.
The private bathroom is a plus. Also, the bedroom and bathroom are located a bit separately from the rest of the apartment, which affords very nice privacy.
It is definitively good value for what is included and where it is located.
