Gilbert (pronounced as Jil Berr) home is at a very central location near to arc de triomphe, gothic quarter and el born neighbourhood. It is 3 min walk to arc de triomphe metro as well.
The room is large and cosy and Gilbert takes effort to clean up the room every day. Very lovely gesture!
The toilet is next to the room and very convenient.
I would definitely return to Gilbert house again if I visit Barcelona given that hotels will easily cost around 120-150 euro/night in that location.
