Prices are uneven, it depends on the city. In Madrid I would say prices are stable. In San Sebastián prices probably went up. In general I think prices are stable or going down very slowly.
There seems to be a global real estate bubble, fuelled by the irresponsible actions of central banks (FED, ECB):
Pandemic fuels broadest global house price boom in two decades
Spain has areas that are as congested and densely populated as NYC or Shanghai (near Barcelona for instance: L'Hospitalet de Llobregat - it's a built up ugly town, looks a bit like China actually), and places where no one lives (maybe 85% of the country's surface). In the "empty Spain" there are less inhabitants per sq km than in Lapland. There may be opportunities in some spots of the empty Spain for rural entrepeneurs or online businesses (logistics).
I would say some Eastern European countries have retained some industry, as subsidiaries of German producers, or linked to German manufacturing. Maybe the Czech Republic or Poland still have some industry. Switzerland is another country that maybe still makes some stuff even if it is just watches... (luxury ones). Spain produces few things really, relative to the size of its economy. In my opinion a developed country should not focus on just serving beers to tourists. It's not a great plan for the future.
I think Spain should have moved on to technology, IT services, defence (this is an ok sector in Spain), aerospace, etc It would be great if capital was invested in industries that may have a future even if there is an economic downturn.
Tourism after all depends on the economic cycle and people cut their spending first on unnecessary expenses, stuff that is not essential like going on holiday or eating out.
The health care system is pretty good, but now the COVID-19 incidence in Spain is around 700 cases per 100.000 inhabitants. In Barcelona is close to 1.000 cases per 100.000 inhabitants, so hospitals are really overwhelmed, postponing surgeries etc just to take care of COVID-19 patients.
Still, our government opened up the borders to tourism without any other consideration than the economy.
