Dear Guest, Thank you for your review. We are sorry that you experienced some issues during your stay. However, we would like to point out the actions we took and the options we gave you during your stay. - We sent our Maintenance man to check the issue very quickly after you communicated the issue. - He helped you by providing his mobile phone as a hotspot which allowed you to connect to the internet. - He also found out that the WIFI issue was not an issue of the router in our apartment but a network issue of the Network Provider. - We contacted the Network Provider who confirmed that the network issue was covering a larger area of the city and it would take between 24 and 72 hours to resolve it. - We communicated this information to yourself and offered you a full refund in a case that you needed to be relocated to a new accommodation. Unfortunately you did not reply. - We then offered you 10% discount for the days you did not have the WIFI coverage. So there was really nothing else we could have done to resolve the issue. With regards to the mattress we are sorry to hear that it was not comfortable. However we would like to point out that the apartment has two bedrooms and the bed in the other bedroom was also available for your use. Kind regards, Andrea
