Thank you very much for your comments. We haven't received any complaints about the wifi connection during the period of your stay, otherwise we would have checked it, because we know that wifi is essential for all our guests. The truth is that it may not be equally good in every corner of the apartment, but it is definitely fine at least in the living room.
Regarding the cleaning, since you arrived before the standard check-in hour, the apartment was not yet cleaned by that time, and this is why you were asked to wait. The cleaning took a bit longer than usual, and we would like to apologise for having you waiting.
The apartment size must have been a matter of expectation, since the pictures show it all without any exaggeration. If they were not accurate, we would have had constant complaints about the wrong apartment size, but we haven't had them yet.
In any case, we thank you for sharing your impressions with us, since we aim to improve our weaker points and provide the best service. We hope that you enjoyed your time in Barcelona in spite of the issues you listed.
