Sirimiri is very well located next to the old center. Rooms are big and comfortable. Nice big bathroom with window and bathtub. Check out is rather late (12.00) :)
There is a free private parking. Staff is easygoing and very helpful.
I would surely come here again next time in Bilbao.

If you donot want to spend too much money on a hotel, this lovely small family hotel with its kind and helpfull reception is a bargain. Rather big rooms, very clean, renovated bathroom. The hotel is well located in the Atxuri district. We arrived by car from France and had no problem finding it. The entire city is within walking distance, however the Tramstop is around the corner. Very near the famous Pintxos bars and restaurants in the Casco Veijo. Free Secured Parking. We will return to this lovely hotel.

Our only reason to visit Bilbao was the Guggenheim Museum. This hotel is not near the museum and it is in a secluded area that is unsafe and in the middle of a construction area. It's not easy to find, if you blink you'll miss it. I would not stay here again.

It does the job of offering a clean room and bath, and bed--even had free parking ON SITE. Near the Old City--within walking distance, it was fine. Only drawback was it was the only hotel of about 8 we stayed in--that had lamps so low (only two too) that I couldn't read in the room. But given there was CNN International, que sera.
