Pablo himself is very friendly and helpful. the apartment is well located and good value for money.
the main issue is at the moment the boiler leaks and the shower pan leaks flooding the shower room floor. because the apartment is small, it's difficult to ventilate so this issue makes the space smell damp.
other small issues: the towels were wet when arrived. there were some lightbulbs not working in the room. blankets were provided but it was a bit cold for winter so could have done with a duvet.
with some small and easy fixes, this apartment will be ideal for exploring Barcelona.
