The apartment had a modern interior and amazing location - just 10 minutes from the city center, stores and cafes nearby, and so on. The communication with Quim, the one responsible for the apartment, was also quite okay, we were receiving responsible replies for each of our questions. The price was too high. I realize that it was connected to the fact of organization of an event in the city, and almost all of the places increased the renting prices, but anyways, it is not correct to almost triple the price for some specific days. And why I decided to inform on this, is because the apartment had dust all over the tables (dining table/coffee table), which meant that the cleaning service was done not decently. I assume that in case of charging for such a high price for the stay due to some activities in the city, the apartment owner could place her/himself in the shoes of the guest(s) and try to at least compensate that higher price in form of making everything at the apartment be as clean and comfortable as possible. This is a pre-requisite of a great apartment in any case, but taking into account the high prices, this could be a great compliment to the guest. Also, the Akiles software for opening the doors did not work properly many times. Almost every time we were trying to open the door with 4 devices, both via the Wi-Fi and Cellular internet and it as taking about 15 minutes to succeed. The door on the street opens easily, but one of the apartments did not, and there was no backup/alternative option to open the door manually, the codes did not work, etc. This is a true problem, especially when you need to take the luggage and hurry up for the flight, train, and so on. Overall, once again, the location and interior are quite convenient and cozy. By giving 3 stars to our stay I would like simply to bring the attention of all the apartment owners to not increase the prices for such a huge percentage due to an event. This is not truly correct, I guess. But anyway, thanks for the services, Quim, and please do not take this personally, we are thankful for the support and overall communication you had with us. Stay healthy and hope to see you soon in Barcelona! :)
