This apartment was just like the description and photos, very modern and clean. Ana helpfully answered my questions before we booked. The kitchen was well equipped (except that an electric kettle would have been faster, and cheaper to run).
We live in a very quiet area at home and found the bedrooms a bit noisy at night despite the double glazing. This is because the rooms are at the front of the flat, not on a main road but close to one. It was motor cycles father than cars. Many people wouldn’t notice it and I resolved the problem with ear plugs. Most properties in Barcelona are probably similar unless the bedrooms are at the back.
The beds were exceptionally comfortable, and new bed linen and towels were provided after we had been there a week. There was plenty of storage space. Shops, a market and eating places are nearby. If you go in the winter as we did, the heating is fine and works well, and you do need it especially at night.
The owners are very friendly and helpful, and someone came the next day when we had a query.
The location of the apartment is excellent because the airport bus (runs every 5-10 minutes) stops about a minutes walk away. A metro station is just as close and you can walk easily to the tourist office and into the old centre. The big wide roads, often with trees, of the Eixample area where the apartment is located, appealed to us more than staying in the old centre where there is less accommodation anyway.
I recommend the apartment and Barcelona itself. After 16 days there we still didn’t see all we wanted to! The modernista architecture is wonderful.
