What's Juan xxiii area like for holiday home?

Santa Pola ? Typically Spanish, no full English breakfasts or roast dinners there ! 10 mins from airport, lovely beaches , great harbour and main square 

San Juan xxiii probably not a good choice. Prices are cheap probably because nobody wants to live there. It’s also not near the beach.

Further out there’s San Juan D’ Alacant and Mutxamel. I’ve just moved to San Juan D’ Alacant. At the back end near Mutxamel. Outside my door are supermarkets, bars, restaurants etc. There’s a bus stop for the beach at San Juan Playa and Alicante. The playa bus probably goes near the tram stops at San Juan Playa, easy to get to Alicante City.

Internet speeds are good 50-150mb on 4G and the option to have fibre optic up to 1GB speeds.

There’s some English language spoken. San Juan D’ Alacant is about 20 mins from the airport. 

Further down the coast is El Campello. Good access to the beaches and the tram to Alicante city.

San Juan XXIII covers a huge area, close to Virgen del Remedio to the west; the 2 tramline to the university to the north west; Gran via and Vista Hermosa with their modern malls (Mercadona, AlCampo, MediaMarkt, Carrefour, Primark) to the south; and the beaches and suburbs of Albufereta and San Juan to the east and south. 

It is well connected by bus and tram, but during this last year I have walked the length of it NW-SE on most days, including to the beach, without problems.

The Ayuntamiento is taking positive steps to upgrade older pockets of housing and nearby there are the hospital, health centre and good bus and tram connections.

Hi Mike 

Just letting you know, the post youve answered is from 2019. Look at the first post &  the date  will tell you how old the topic is

The neighborhoods of Juan XXIII, Virgen de Remedio, Colonia Requena, and Virgen del Carmen, among other neighbors are grouped into a category called the "Northern zone neighborhoods" by Alicante's townhall.  
These are not only some of the lowest income neighborhoods of Alicante, but of all of Spain.  They are high crime areas, with high levels of drug trafficking.  There are also a high number of squatters living in homes.  Many people don't pay their dues(usually around 240€ yearly in this area) to the building's maintainence association(la comunidad de propietarios), thus the vast majority of the buildings common areas are becoming dilapidated, have sewer drainage problems, leaky roofs, and other problems, as there is a lack of money for upkeep.  
In terms of police, the local Alicante police usually don't enter these neighborhoods, and will outright ignore calls, if you call them.  Many delivery services, whether food, etc. also refuse to enter these neighborhoods.  Nevertheless Spain's National police do respond quite quickly when called, thus it's always better to call the national police and not the local police.
In terms of housing prices, the houses in this area are hugely discounted and about 70% cheaper than a comparable house in the center of Alicante.  Which despite all the problems, still makes the area possibly worth considering, but be very careful about choosing which building and where you buy an apartment, it is wise, and by far the most important thing to do is to investigate the  building's maintainence association(la comunidad de propietarios) to see if it's working, so you won't have problems with he building being declared uninhabitable and marked for demolishing. 

That is an outdated and unhelpful stereotype. 

Modern blocks, supermarkets and malls like Gran Via are being built and more outdated blocks have been renovated.

The last paragraph has some relevance. Wherever you choose to live, make sure the local authorities provide and community maintain basic infrastructure and services in ''your'' building. The northern area is high enough to avoid flooding and mosquitoes and the frequent trams (10 minutes) buses (20 minutes) quickly reach the city centre and beaches.
