Giulio was very good as a host. He helped us get to the apartment when I could not follow the Sat. Nav. correctly, partly due to a 3 hour delay on the flight from the UK.
If you are driving, a small car is an advantage as the parking is underground. I managed to get an Alhambra in and out, it just took a little more effort.
The location is great for the Metro. Placa de Sants is only 5 mins away, so if you are arriving without other transport it is convenient to get too.
We only stayed one night to break a journey. The facilities are all there and the kitchen has everything you need. There were 5 of us and that was OK for the one night and probably a couple more. Any more than that and I think it would have been a bit crowded. For two or three people it would be a great base for longer stays to see the sights of Barcelona.
Giulio was very attentive and let us leave the car parked whilst we went sightseeing. It only required a text about 30 mins out, to let him know that we were on our way to collect the car.
Overall, I can thoroughly recommend this flat and Giulio for a stay in Barcelona.
