I stayed here 5 nights during the lockdown period.
Communication with the host was good. His friend checked me in and was on time and friendly and showed me around the apartment.
The location is very good. It is a safe neighborhood and has excellent transportation options: 10 minute walk from Barcelona Sants train station, five minute walk to Pl Espanya metro stop and the Aerobus stop (near each other). A short walk to several different grocery stores and Hostafrancs market. A short walk to Arenas de Barcelona.
The flat was very clean upon checkin.
The balcony has a table/chairs and is very nice and sunny - much needed during the lockdown period!
The flat has a lot of space with 3 bedrooms for sleeping and 1 bathroom. It has a washer and dryer (and also a drying rack). The kitchen is good for cooking.
The only issue I had was some noise from the flat above.
