I was travelling with my 1 year old son and extended family.
Taxi from the airport is about 45 euros. The apartment is in a good residential location with amenities like restaurants, bakery, supermarket etc downstairs, The lift us a little small but doable with a buggy.
On arrival, Lida showed us around, helped with the luggage and went through the house rules with us. The flat is spacious and well equipped for a family. It is quiet as well at night.
The wifi was good as long as not everyone was logged on at the same time.
A couple of snags....1) there was no microwave in the apartment- just an oven
2) Please be aware that unlike the other flats we booked in Spain where the price quoted was for the number of adults in this case the number of people has to include the baby so make sure you let them when making the booking,
3) the air conditioning is only in the living room
Location was good for metro links into the centre from Maragall station and was great for exploring the city,
Tip- the bakery downstairs is brilliant for breakfast supplies!
