Naiara’s apartment is directly beside the football stadium so is well located and within easy walking distance to the Guggenheim, city centre, old town and Termibus (where the airport bus arrives and departs).
The apartment is as per the photographs and is really lovely. We stayed for a weekend visit and found it clean, comfortable and convenient.
The only negative feedback we encountered was regarding check-in as Naiara’s check-in times are strictly between 4pm-8pm only. This was not clear on the listing and we only learned of this on the day before when we were in touch to confirm our arrival and key collection details. We flew in from London later that evening so it was quite stressful and difficult to arrange this - following several emails, Naiara did sort it in the end with a friend who met us, however I recommend a lock box for self check-in or leaving the key in a trusted safe place nearby (a shop/cafe/restaurant/neighbour) for ease and flexibility with future guests.
