First of all, Ricardo is a nice person who will proactively give you some precious advices and even help. Thanks to his appreciated assistance we managed to find a park lot at an affordable rate which is very convenient as parking lot prices are very high in Barcelona.
We were offered a bottle of local champaign upon our arrival. It is always nice to receive such gift especially during this period.
The place is well located. One station away from Catalunya Place.
The apartment is big and nice. You may hear sometimes the noise of the metro but it is not that uncomfortable.
Ricardo sent us a link with a website which gives you lot of advices, places to visit and addresses. Which is helpful.
