Pro:
Convenience: It is very close to the Barcelona metro (Hostafrancs) and also walking distance to the Barcelona Sants Train station. Maybe a 15 mins walk to Pl Espanya station, where you can take the train to Montserrat and also the Aerobus (bus to the airport). About 20 mins walk to the Magic Fountain.
Local: It is very quiet here, no tourist. There is a local market and supermarket on the street. So you can experience what it is like living in Barcelona as a local.
Host provided a mini bar, but I do not believe it was necessary as the market is just a few steps away. This place is just what the photos shown. It is a small apartment, but is clean, neat and tidy. It was enough for 4 people to sleep but not more. There was enough hot water and the pressure is good even on the 3rd floor.
I would reserve this apartment again if I know that I would use the train stations listed above.
Con:
Impersonal: It was run by an entity and not a host. At least 2 people handled my account. 1st one gave me the wrong apartment number. I had an issue checking in. However, it was immediately resolved when I called the emergency number provided near the key box.
Missing amenities: My apartment had no soap or shampoo.
Delayed response: I WhatsApp them to inform them about having no soap, there was not response.
Since I only stayed for one night, we used the hand soap. It could have been a better stay.
