We stayed at the apartment for 3 days. The apartment is clean and nice we really enjoined the little balcony it has, after long days in the city you can chill there in the night. The neighborhood is safe, has a lot of little caffes, shops, tapas bars etc. and basically it takes you like 10 minutes to get to la Rambla and Gothic quarters - really well located. Also connection with the airport is super easy and quick.
Rodrigo is very helpful, nice and responsive when you text him or email him. I would totally recommend this apartment for your stay in Barcelona. I would use it again if I would ever come back to Barcelona.
Thanks!
