This is a really nice Airbnb in the Barceloneta neighborhood. The neighborhood feels really authentic and it is located in a really good place. Very quick 5 minutes or less walk to the beach and outdoor gym. Very close proximity to 2 grocery stores (Caprabo & SPAR). Plenty of nice small restaurants, bars, and cafes in the area too. Public transportation to several buses are just 4 minutes away and the subway is only about 8 minutes away. So the location is fantastic.
The apartment is very small, but you can clearly see that from the pictures. There are two small bedrooms, 4 chairs at the dining table, and two "living room" chairs. the Wi-Fi works well. There is also a stove, oven, fridge, freezer, microwave, ironing board, and washing machine. The shower heats up water extremely quickly but the hot water only lasts for about 20 minutes (enough for two showers). The entire apartment looks recently renovated and thus it is very unexpectedly nice compared to the building and hallway you enter through.
We stayed 31 nights in the apartment and when we checked in we had to sign a rental lease and an inventory sheet. This was a surprise for us since Airbnb is meant to be less formal than that, but the owner said it is Catalan law, so keep that in mind. Overall it's a great place to stay in Barcelona, you can't go wrong if you just need a nice clean small apartment in Barceloneta.
