We've stayed at Picasso Suites end of April 2015. We had a great time in Barcelona, in no small part, thanks to the awesome accommodation. The apartment itself was in immaculate condition, greatly appointed, well located. The hosts were extremely helpful, helping us organise the bikes, lock them for the night in the garage, or helping out with local tourist information.
We're airbnb hosts ourselves and I know what takes to give someone a great service. This was definitely one of them. We'll be back for sure.
