The apartment is located in a very good area - close to the sagrada familia. The flat is pretty big, but one of the rooms is super tiny and one of the double rooms the bed is very low, so careful if you travel with your grand parents. It is an interior flat although it has good light.
In general the flat needs an update as the kitchen and bathrooms are very old (I would say the original from when the flat was constructed) and it needs definitely a paint job.
During our stay, the TV was not working at all, despite the fact we shared this with the handy man and the owner, nobody came to fix it in 6 days.
Also, we were requested to pay (in cash) some fees for late arrival + the city taxes, 96 EUR total, and we are still waiting for the invoice…
Definitely expensive place for what you will get.
