this is actually not really a deal but a regular BAR rate for this property offered by Tourico (the owner of easyclicktravel) through all of the connected sites (e.g. as well through their sister site lmtclub.com) ... whilst not always available, it is common to be priced this competitively throughout the year.
unfortunately, the property is not really a joy to stay in, though really a steal most of the time...
