The experience at Hostal Siesta And Go has been one of my worst ones in terms of accommodation, and that after travelling through many countries and cities in the past years. I went to Madrid for an important exam at the Embassy of Austria on Sunday, January 16th, 2022, and looked for a quite, simple and clean place next to Nuevos Ministerios where I would be able to rest from Saturday to Sunday. Comparing different offers on the AirBnB website and by looking on the available pictures, I found the Hostal Siesta And Go to be a reasonable option to stay for a night. As I arrived there, I was still believing to stay in an adequate place, as the main foyer was an area with natural light and windows, matching the pictures on the website – unlike the other parts of the hostal. As I followed the guy in charge through the door leading to the inner hostal area, I was shocked and highly dissatisfied at the same time: The hostal itself consists of one long, windowless hallway along which there are several bunk beds with almost no privacy at all. All the walls were painted black. It rather seemed to be a tunnel below earth and was surely a former industrial warehouse. All the guests that stay at the hostal need to pass along all other guests to get to their beds, disturbing them and exposing them to permanent noise and light. At the end of the hallway there were some individual rooms, one of which was mine and I had paid € 30 for. My room’s size was about 2,5 square meters, walls painted black, no ceiling lamps, but improvised floor lamps. The smell was like in an underground space with seemingly no ventilation at all. That’s why there were many air fresheners placed all over: to cover the smell and the quality of air. The ventilation system consisted of ceiling ventilation stacks that did not manage to make enough air flow. I felt uncomfortable, breathing used air full of CO2, and that in times of COVID. The regular toilets were not working either. Instead the toilets for disabled people – where also the hostal’s waste was stored – had to be used. Disgusting! In the end, when I finally managed to calm down and go to bed, after all, I overheard every single word the people next door, in the other chambers, were saying, as walls seemed to have been made of very thin material, with no soundproofing at all. Maybe the Hostal Siesta And Go is an option for exhausted travelers who directly arrive from the airport and have no choice but to sleep anyway after their trip, but in my opinion this place needs to be shut down immediately. I have also informed AirBnB and the local chamber of tourism and ask the platform for a full refund. I kindly ask all fellow travelers to also report the insufficient conditions you were exposed to and to assure that similar places will not be able to function in the future. Help the community to make their travel experience pleasant.
