The apartment was delightful: we really appreciated the classic brickwork, creative lighting and attractive fabrics on the bed and settee. The bed was very comfortable and, whilst the balcony wasn't large enough for two people to use for eating, it was a lovely addition. There was sufficient wardrobe space and the bathroom was a good size, with great lighting and lots of shelf space for cosmetics. The location is excellent for travellers like us who are coming from the UK. It's close to Espanya - where we caught the airport bus - and within walking distance from Sants. It was, however, very noisy, made worse by the building work taking place outside, but the shutters were effective in containing the sound and it was good to have air conditioning, which we used at night to stop the apartment from becoming too hot.
We felt that the basic provisions were a little lacking. There was no washing-up liquid, so we had to use the shampoo left in the bathroom, and only two toilet rolls were provided - not enough for a four-day stay. The sofa bed is large but an additional easy chair would have been welcome. Our son visited us in the evening and had to sit on a hard chair. However, overall this was one of the nicest apartments we have stayed in during our regular visits to Barcelona and we will certainly try to book it again in the future.
A note for Airbnb: we were surprised at having to send photos of ourselves and our passports on our arrival, along with being asked to pay the city tax via a Barclays app. This is the first time it has happened to us so it is probably due to Brexit, but it would have been helpful to have been warned in advance that this would be required.
