The location is excellent. It's easy to assess Av Diagonal, Psg St Joan and Psg Gracia for all of the most iconic shops, restaurants, and clubs. It's very close to the Sagrada Familia and 2 blocks from the Girona metro station. Below the apartment on the first floor of the block are 2 super markets, 1 decent restaurant that opens until 11pm. At the closest intersection are cafes. It is a typical central Barcelona block where you have everything you need.
The apartment itself easily caters to 4 adults. The WiFi is super fast (120 mbps download), allowing for streaming or video calls. The bedrooms are comfortable, there is good AC unit in each room, the water pressure in the bathroom is excellent, and the kitchen as everything you need (stove, fridge, microwave, coffee maker, plates/dishes/bowls, utensils, dishwasher) and there is a washing machine in the back balcony.
