Hello Angela :)
Thanks for this useful review as I will try to improve from your opinion.
The wifi signal aplificator sometimes gives my guests some conection problems, I am working on it. The person from the technology shop told me that that hapens to this kind of devices, and it does not hapen very often but I have an eye on it.
About the construction work, I am sorry. It is not in my control if my neighbor decides to do some construction work. I understand that it is very anoying.
In my Airbnb profile I have indicated that there is a dog in the house, so everybody knows that before doing the reservation. I already had is signaled before you did your reservation. I did it as soon as I adopted her (the dog).
I have to big fans now, for the summer season, so from now on guests can make the air flow much easier, as summer in Barcelona might get hot and stuffy, as you said.
With that being said, I hope you have a nice day.
