Asier welcomed us very warmly, gave us very helpful tips on where to eat and what to see in San Sebastián / Donostia, and made sure we had everything we needed. What a perfect host!
The very clean, modern, private room (#2) was quite spacious for two people. It has large glass windows on two sides, but still private, as there are no buildings that look into the room. The solid door has a lock so you can leave your valuables in the room all day. The large wardrobe has hangers, a shelf, and fits a carry-on rolling bag. The electronic shutters were a nice surprise, and keep the room completely dark when closed (or they can let in a bit of spotted light when closed a certain way). The double (or queen?) bed is one of the most comfortable Airbnb beds, it makes you want to sleep all day. Wifi is not the fastest but decent enough to get things done.
The shower/toilet in the hall is shared with another room. It is very clean as well. There is plenty of hot water.
The free breakfast was also very nice (toast, jelly, coffee/tea, orange juice, cereal).
If you are visiting with a car, this place is perfect because you can park your car in the house garage for free. It may be confusing at first to find it with Googl Maps, so make sure you get good directions from Asier.
If room #4 is available, book that because it has an en-suite shower/toilet. Otherwise the other rooms (including this one) are still excellent.
There are two dogs on the property but they are quite friendly and kept away from the common areas at all times.
I highly recommend this place and would stay here again.
