The timing isn’t good, but your best bet is to ask for a full refund because the unit as it was listed is no longer available.
Sometimes, unforeseeable renovations have to be scheduled. We had a category two windstorm in a mountain town where I live, and I found myself on the roof having to do repairs. Sometimes there’s Damage from previous guests. I can see the host didn’t want to cancel your trip entirely and offered you a discount for the loss of the room. Still, if you want a space with two rooms, I would ask for a refund and try to find a place. It’s difficult when you land and have to find a place, but You sound young enough to be agile and capable of adventure. I hope you and your friends can find another place with the multiple spaces you need, or take the €150 and make a night of it 🎉
I’m sorry, I don't have a better answer to stuff like this. But I can see the host is trying to still be available. You just have to decide whether or not that’s good enough and if it’s not good enough there’s always the option of asking for more compensation. but please keep in mind this host has tried to provide you options rather than just cancel and I hope you wouldn’t give them a bad review because of that. our business is conducted in buildings and unfortunately they have to be repaired and renovated frequently in order to keep up with the standards of hospitality.
begin this conversation before you walk in the door cause it’s a lot easier for a host to just give you a full refund and not have to send a cleaning crew back out and you guys find a new spot then after you get there drop all your bags and rest and then ask to cancel
despite your lodging hiccup I hope you have a good rest of your trip
