On a last minute get away to Madrid we made a VERY last minute accommodation reservation (the night before), booking the apartment on the strength of the photos provided. Perhaps in our haste we did not realise at the time that what we were looking at were a whole host of other apartments owned by the same host and not ones specific to where we would be staying (I have maybe been using a certain other booking site for too long). When we arrived in Madrid I searched out the address where we were to go to and noticed for the first time the two words that have come to haunt me.. 'Deluxe Studio'. I tried to contact the host from the airport to explain we believed we had booked a 2 bedroom apartment but spent about an hour trying to navigate an automated voice system that kept telling me to either email or whatsapp. Frustration building, I eventually gave up trying to get through to speak to an actual person and emailed, and to be fair did receive a fast response. I explained the situation but was told that this is what I had reserved with a mention of one bedroom, so resigning myself to perhaps sleeping on a sofa bed in the main living area we made our way over to the apartment.
On arrival we opened the door to be greeted by a single room, no divide, no separate spaces, the sofa bed I had resigned myself to sleeping on a mere hairs width from the main bed. Realising we were in hell I got back in touch with the host to see if we could change to another apartment; fully booked, sorry. If we could cancel our reservation or reduce the 4 days to 1 or 2 so we could look for a different apartment that suited our needs; this is what you have reserved so no, have a nice stay. No matter what I tried to negotiate with the host they were not interested. I explained we had been misled by the photographs they used but they couldn't have cared less, we had been duped, our cash was in their pocket already.
After spending nearly the whole of our first day in Madrid trying to sort this out I gave up. We stayed in the apartment for 2 days until it became unbearable and booked into somewhere else; a lovely spacious 2 bedroom apartment, and breathed a sigh of relief.
Pros - Clean, modern.
Cons - Small, no real time contact with the host, misleading photographs, unscrupulous - make sure you read the small print.
