So glad my mum and I chose this place for our week-long stay in Barcelona. The location is a traveller's dream - non-touristy, close to tapas, there's a bakery and fruit and veg place on the street, and close to Poble Sec and Parallel metro stations. Supermarkets on Parallel are abundant too. Not to mention the walk to the Gothic Quarter and the water is easy. We loved going out all morning, coming back for a siesta, then going out for dinner and a wander.
Yes, it's an old building with hallway smells, narrow stairs and floor creaks - it was built in 1905, so this is an authentic experience. None of it bothered us. The stairs may be a problem if you have accessibility issues; if you don't, and you brought a super heavy suitcase that you can't carry up the stairs, well... you probably overpacked.
We loved cooking scrambled eggs and jamon for breakfast, with delish Nespresso coffee. Highly recommend the 1 and 1.5 euro tapas joints on Carrer Blai. Thanks also to Camille for meeting us and giving us some tips, and Vincent for his quick answers.
The only recommendation I've made to Vincent is to perhaps ensure the shower head can remain attached to the wall... holding it and shaving your legs requires some circus skills!
