The apartment was very easy to find (a few blocks in from the running track by the seafront). Javier showed us around the apartment and how to use various items so that all was clear. He even contacted us the next day and just before leaving to make sure everything was okay.
The apartment is in a superb location. It is only a few blocks from the beach and ideally situated away from the crowded main tourist areas (although these can be easily reached by a pleasant stroll along the seafront or a few stops on the metro).
There is a well stocked supermarket on the same street as the apartment (Día) and larger ones (Mercadona / Lidl) within a 5-10 minute stroll nearer the Poble Nou Rambla. This Rambla has a charming array of shops, restaurants and cafés.
The apartment itself is very stylish, comfortable and spotlessly clean. The kitchen, and apartment in general, is well-stocked of amenities and it was great to relax there after a day at the beach or exploring the city. The beds were so comfortable! Javier has really thought of everything you might need. I would stay in Javier's apartment again.
One note to those who are unfamiliar with Continental apartment-living. The construction of properties for warmer climates means that carpets are rarely used, therefore sound does travel. Earplugs are a good thing to pack if you aren't used to hearing noise from those around you as they go about their daily routines...remember that others aren't necessarily on holiday!
