The apartment itself was ok -- it is comfortable, with almost everytjing you may need for several weeks of stay. But the service of SingularStay was absolutely terrible. At the day of our arrival, when me, my wife and our two small kids were at the train heading to Valencia, SingularStay's manager wrote me that I need to sign an aggreement and to pay additional 400 euros as deposit. These conditions were not mentioned when I made a booking via Airbnb, so I contacted Airbnb support and they confirmed that SingularStay violated Airbnb rules. They suggested to cancel the bookingwith full refund and find another apartment. I finally decided to pay this 'deposit' to SingularStay, because we have already arrived to Valencia and needed place to stay. Now in 2 weeks after our check-out I still haven't got my 'deposit' back. SingularStay's managers refuse to answer my requests for rufund. So, my advice to everybody -- do not book apartments listed by SingularStay, if you don't want to be robbed
