Can the landlord raise our rent

The landlord can raise your rent once out of the agreed leasing period. This is not the first case of greed with which I have come in contact. Your landlord hasn't a hope of renting out the place during the summer as the season is as good as dead. Even today the Irish minister for health advised that if anybody somehow travels to Spain this summer they will have to self-isolate for 2 weeks on return. 

I came across situations such as yours when the ash-cloud problem kicked in some years ago when a landlord wanted to screw his off season tenants over Easter when flights were cancelled and he wanted increased rental. 

If I were you I would approach the landlord/agent and put the case to him/her. If they don't come to some sort of amicable agreement, then find somewhere else to rent and don't do business with the landlord again. Ensure you get your deposits returned to you too. 

See response on other thread - I recall seeing that rental contracts that terminate during state of alarm by law must be extended by three months.
