Temporary 105 m² flat in Esplugues, listed at €2,500/month. The description mentions short luxury stays but does not state furnishing, bills, deposit or minimum stay.
Sant Martí stretches along the coast from Poblenou to Diagonal Mar. Poblenou's old factories now house the 22@ tech and design district, next to a quiet pedestrian rambla and several city beaches.
Metro L4 runs parallel to the sea and the tram covers Diagonal. It suits people working in the 22@ area and anyone who wants the beach within walking distance, with newer buildings than in the old town.
City
Barcelona packs ten districts into a compact, walkable city between the sea and Collserola hills. Metro, buses, trams and FGC trains reach almost everywhere within 30 minutes.
Medium-term furnished rentals (1–11 months) are common for people relocating; long-term unfurnished leases follow Spain's tenancy law (LAU). Expect a deposit of one or two months and agency fees paid by the landlord.
