Hi,
I lived in Monica's house for a week which is a very good experience in Barcelona. This house located in a residence area where you can easily find supermarket, bars and restaurant nearby. For transportation is easy too. Only 5 mins to city central such as Jaume. Also this house is 10 mins to the beach. Very beautiful terrace. You can enjoy your breakfast inside or outside. Everywhere in this house is super clean.
Monica is a super nice host. She help me to know tips and sightseening spots in barcelona. She even invite me to have dinners with her friend. We had great time and become good friend.
Perfect house and location, I highly recommend it.
