Communication is great with Hector. I was coming in, last minute, earlier than planned and he was very kind and considerate to offer to help me locate a place as my room was already booked for that night.. He even stored my storage a day before I was anticipated to stay the night.
The room i stayed in was perfect for the single traveler; storage is simple but ample. The apartment itself is really nice with great cross ventilation, so there is a great summer breeze that cuts through the apartment.
The location, for me, is great, it is near Sants train station, easy to come in with your luggage and settled down to explore the city. I like exploring the city via bike and it was super convenient that the 24 bike system, Donkey Republic, is right around the corner. If you are on an extended stay just rent the bike for multiple days.. so convenient to explore the city and easy to park.
I stayed close to a week at Hector's and definitely recommend it to anyone interested in exploring Barcelona!
