The apartment is in a very nice location, it is not too noisy and you feel very safe (also because the apartment has an alarm). Metro stations are very close by, so you can acces every part of the city very easily. Good restaurants and shops are also in walking distance.
We were greated by Lauras mother who was very welcoming and nice. Laura, the host, is also very friendly and checked several times with us if everything was going nicely or if we needed anything. She was so kind to call us a big taxi for the airport, which was very helpful.
The apartment ifself is nicely decorated and has everything you could possibly need, Laura even left some snacks and water! We also enjoyed the balcony and the aircon very much, as it can get hot in Barcelona.
