Hello! I am from Argentina and I will be in Mainz the last days of April looking for a furnished apartment and with services (i.e water, electricity, Internet) included. I’m a Ph.D. student in Chemistry and I have a scholarship to make a short research stay.
I need an apartment available from 1st May (or few days before) to 9th October.
I can see the apartment from Saturday 27th April onward when I arrive at Mainz.
I wait for your comments as soon as you can.
Thank you in advance for your attention.
Best regards,
Milagro
