Eli and Agus are super host :-)
They are very responsive within hour.
Everything you need is there — Home Sweet Home. Clean and very organized. We closed the shades to keep the apt cool; must be great during winter. Balcony view to La Sagrada Familia.
They allowed to leave our luggages before check in and after check out. This is substantially important and made our stay much smoothly.
The apartment is Central to everything as mentioned on the listing. It is close to Metro monumental station and other bus stations.
If you buy a 24 hours or up to 5 days (120 hours) HOLA Barcelona travel card, you can hop on and off Metro, bus, FGC, TRAM and Rosalie’s train (ZONE 1 only for all). We have a great time traveling around simply using public transportation, including Abbey Montserrat visit via R5 train / cable combination.
Kserol, nearby restaurant, recommended by owner, is pretty good. Lots of bakery around.
If we ever come back to Barcelona, we would love to stay here again.
Tips
If you are interested in all those popular tourists attractions during the peak summer season, buy all the tickets online a week before (from official sites). Less tourists during early hours; best time and guide tours would be fully booked.
