Edu is a very nice and helpful host.
The location is the best possible. In the very centre so it's quite noisy BUT with windows closed you hear nothing, so no worries. Walking distance to most places of interests, supermarkets and bars are just downstairs.
The apartment is well equipped, beds are comfortable. The only thing we missed were wine glasses and softer towels but these are just little details.
When back in Barcelona for sure will stay here again!
