Great apartment, just like it is advertised. Mariela our host was very welcoming, walked us through the aparmtent and recommended reataurants, places to visit, etc .
We were 5 friends celebrating a 'significant' birthday together! We found the apartment to be very clean, plenty of everything in the kitchen, nice seating area, two bathrooms, both with showers, brilliant for five women! Beds were comfortable.
The apartment is in a residential building, no noise after 9pm, this is expected and respected. There is a small elevator, it holds two people, apartment is on the third floor. WiFi was hit and miss, but didn't bother us much.
There is a supermarket a quick two minute walk from the apartment, turn to your right when on the street and take the first street on the left. There are coffee shops and restaurants close by also.
Easy walking distance to La Sagrada Familia(10-15mins), Casa Batllo(5-10mins) Palau de la Musica Catalana 15mins, The Gothic Quater about the same.
All in all this apartment is an excellent location for a city break, we were very happy and would book again.
