My family and I had a great time staying at Jacques apartment, the place was nice and clean and has everything for a short or long stay (dishes, glasses, kitchenware, washing machine, etc.), we were provided with a welcome kit with coffee, tea, sugar, soap for the dishes and the washing machine, which was really useful. The elevator in the building is small and if you are traveling with family or luggage it will probably require more than one trip. There is a small supermarket beside the building which is very convenient for primary supplies, there are cafes and places to eat nearby and the Mall Arenas de Barcelona is just a 10 minute walk away, this mall is located in front of Plaza de España which has plenty of metro lines and bus stations which allow you to go anywhere in the city.
Jacques was a nice host and was in touch before we arrived, we had to collect the keys of the apartment in his office, which is nearby, and he even paid for the taxi to take us to the apartment because we were carrying our luggage. The Wi-Fi router was not working and Jacques provided us with a portable router for all of our stay at no additional cost, which was really convenient to be connected everywhere we went.
In summary, we had a nice stay in Jacques apartment and I would definitely recommend it
