The room was spotless and the beds very very comfortable. The hotel is located in what seems a corner of a village at the foot of a hill, so it's absolutely quiet. Actually, it's only 15' from the city center and the airport by car, and there is even a bus stop directly in front of it.
The free parking is somewhat hidden on the rear of the building and was full, but no big deal finding a place on the nearby street.
We were looking for a stopover place during a long drive, so we aimed at price rather than comfort. We got the Tryp at the same price of an Ibis, but the quality we perceived was way higher.

We stayed here on the first and last night of our holiday in the Basque region and we loved our stay!

Fair enough, Sondika doesn't have much to offer. But it is about a 15 minute bus drive into Bilbao (be warned, on a Saturday afternoon all the shops are closed in Bilbao!) and there are lovely restaurants about 10 minutes walk away. Still not a huge choice but we had the best meal of our 2 week holiday in Sondika.

The main reason for us to stay here was because it was close to the airport.

I can recommend this hotel.

We weren't expecting luxury, given the price, but this hotel was still very disappointing. Other than being extremely hard to find - and equally hard to figure out how to get into the driveway! - this hotel really has only one redeeming feature - it's near the airport.

The rooms haven't been painted in YEARS and are badly beat up. The fridge has to be turned on by the front desk. The restaurant was "closed until September" and there is nothing else for miles other than a very inadequate little place right next door (the food there was tolerable, at best).

It seemed reasonably clean, though, and although the bathroom was very small, the shower was nice enough.

I was a solo traveller with a hire car.
It says Sondika but you have to leave Sondika (under the bridge for another half K - if travelling from the east) to see the high-rise sign.
There is free parking - it's not obvious but you have to drive accross the brick area in front of the hotel to get to it.
I've read the other reviews and yes, the carpet in the landing is well worn. In fact the whole place could be classed as little weary and perhaps a lick of paint would make a difference if you are occupied about these things. I thought it all hung together reasonably well, Everything worked, from the shower to the in-room safe, and was clean.
Didn't eat there.
The in-house bar was closed on my night there but there is a bar/restaurant almost next door which I went to for a final beer (or two) - looked ok, but judgement was possibly a little fuzzy by this time.
It's a E15 taxi ride (each way) to Bilbao town centre for all the entertainment you could want. I went to the Guggenheim - E8. I suggest worth the money even if you're not normally interested in that sort or art.
If you are returning a hire car the next day - as I was - turn right out of the hotel, it's about 10mins drive (all signposted) and there's a petrol station on the way to fill up. Stay alert though, at one point you join a motorway for only about 200yds before turning off again ....lord knows where you'll end up if you drift past that....
