In a quiet place, a real Spanish building, you have the apartment of Nunciata.
The shared bathroom is basic.
Breakfast (also basic but with some choice and comfortable enough) can be consumed in the corridor.
The place is in between several metro stations close to the ramblas.
It is a basic (and so low priced) Pbut perfect place for the solitary traveller who knows little Spanish but can speak english into the translating app of the hospitable 'Nunciata'.
My bed was 1.85m. The wifi OK.
