Pros: 1° the location is great (1 min from Sagrada Familia + metro station), 2° photos of the apartment are a fair description of the place, 3° the apartment was very clean, 4°communication until arrival was excellent, 5° price is fine (although see our remarks below)
Cons: 1°, no internet connection despite what is announced in the ad (the internet device is situated in another apartement of the building- and there was no response to our request made on day 1 to have the issue fixed), 2° there was no toilet paper (we bought some), 3° two bedroom doors latches are broken (we were very suprised the first time, then we decide not to close them - no other option in fact!), 3° the building is extremely noising all night long due to very thin walls and lively activities + street noise is very loud, starting before 7 am until midnight at least: this place is in our view not adapted for families with young children and for people unable to cope with noise.
Beware not to arrive at 21:15: we had to pay 25 € fees for "late arrival".
