A Place in the Sun viewers spotted a huge problem with one of the properties host Danni Menzies showed prospective buyers Sandra and Dave during Wednesday's show.
The couple, who have been married for 33 years, said they were downsizing as their children had "flown the nest". They were going to use the money they saved on a smaller home in the UK on a holiday apartment on Spain's Costa del Sol.
They had a budget of around £180,000 and wanted a property with a communal pool, plenty of space for family to visit and sea views. The pair said they specifically wanted a child-friendly pool for their young grandson Henry to use.

Danni, who has spent her life working for her family's property company, was up for the challenge. And as they perused the La Duquesa area of the Costa del Sol, Danni showed them five different apartments.
But viewers spotted a problem with one of them. After being shown a ground floor apartment some way from the sea, Sandra and Dave were left unimpressed.
However, Danni then showed the couple a penthouse apartment with a huge communal pool. It had two bedrooms, two bathrooms and a roof terrace with views of the pool.
It seemed almost perfect, but fans of the show spotted a problem. Taking to Twitter, MJ said: "Penthouse? Small grandchild?...". Mich W said: "Can't have a top floor apartment with a little one!".
More properties the couple were shown included an apartment in a residential area that was a five minute walk from the harbour, and a recently refurbished apartment with two bedrooms that was very close to the beach.
After sleeping on it, Sandra and Dave decided they preferred the final property they were shown. However, they didn't put any offers in as they said they would need to bring their family to Spain to show them it first.
A Place in the Sun airs weekdays at 3pm on Channel 4 and All 4
