Antuan was friendly and helpful on my arrival,he came to the metro station and picked me up and carried my heavy luggage. He gave me some information on what to visit in Barcelona.
The room is small but more than enough for 1 person.There is a desk with a wheeled chair too and helps if you bring your laptop or tablet.
The house is very close to Placa Catalunya which is the city center.Probably 12 minutes with the metros.The Barceloneta Beach is on the same metro line close to the house and the metro station is less than 2 mins walk from the house.Also Night Buses are just outside the house. Lidl is also on a walking distance if you want to get some food etc and there is another small supermarket just outside the house.
If you don't want to spend much on accommodation and be close to the center I would definitely recommend Antuan's house.
