We enjoyed the stay in Ali's flat. Everything was fine, the flat was clean, comfortable and what is most important for us - close to the city centre. It takes just few minutes to get Rambla or any other part of the city from metro station. Ali is replying immediatelly to all the messages.
The only minus was a bit noisy neighbourhood, but I can understand that it is normal in that area.
I would recommend Ali as a host and staying there.
