We loved starting 2023 in Xabi's apartment. We found it to be absolutely gorgeous; very modern and beautifully furnished. The location was a godsend, with tram and bus stops right outside, and we also used the building's pool, gym and sauna a couple of times each during our stay (all great).
Our only critique was a drop in communication shortly after we checked in, regarding the flat's wifi. We couldn't (and never did!) locate the wifi box itself, and after enquiring it was a full day before we received it (this was over NYE, so completely understandable, but as international travellers we had no data access, so had leave the flat to use the internet in cafes etc to contact Xabi).
