The place looks tire, it needs updating. The upside is, it is very spacious (it could be the reason why the cleaning fee is comparably more expensive) and centrally located however it could be a problem in summer when you need to open the balcony doors (windows) as it is quite noisy with cafés operating till very late at night.
Overall, we had a very pleasant stay. St Sebastian is a beautiful holiday destination, we definitely will visit again and stay a bit longer next time.
