Almost nobody at the coliving rents a car for the whole stay, and it is rarely missed. Between walking, the city buses and a cheap bike subscription, everything you are likely to want is covered. For a day in the mountains a car changes things - inside the city it mostly does not.
All three houses sit within roughly a five-minute walk of Playa de Las Canteras. The seafront promenade is flat, traffic-free and about 3 km from end to end, which makes it the default route for almost everything along the coast - including a run or a walk to the surf.
La Cícer, the surf section at the southern end of the beach, is about half an hour on foot from the northern end. Pleasant once, and a lot if you plan to surf every day - which is where the bike comes in.
The city bus network is good and cheap. Vegueta, the historic old town, is around 30 minutes away on line 12.
Google Maps shows live bus routes and departure times and works very well on Gran Canaria - it is the simplest way to plan a trip here.
You can reach a surprising amount of the island without ever renting a car:
Dunes of Maspalomas: 50-60 minutes by bus
Caldera de Bandama: 60-70 minutes by bus, a volcanic crater and an easy first hike
Plenty of other spots are just as reachable, and Google Maps is the simplest way to check how long a given trip takes.
Sítycleta, the city bike sharing, costs €3.34 per month and includes the first 30 minutes of every ride - which covers most trips within the city, including the ride down to La Cícer. There is also one coliving bike and several rental shops. Details in Getting Around by Bike.
Less than most people expect, and inside Las Palmas close to nothing - the time you win on the road you give back looking for a parking space.
Inside the city: a car is barely faster than the bus once parking is counted. By bike you are usually faster than by car.
To towns like Maspalomas or Agaete: the gain is small - these are exactly the routes the buses serve well.
Into the mountains: here it is real. The same trip by bus often takes about twice as long, sometimes with a change.
So the honest split is: for everyday life the bus and the bike win, for one or two trips inland a rental for a day or a weekend is worth it.
Rental companies: there are plenty, at the airport and in the city. If you rent from a company in Las Palmas, you can usually leave the car parked there as well - which takes the parking question off the table.
On the street: parking in the streets around the houses is allowed and free. You will have to look for a space, though, and at busy times that takes a few rounds.
In a car park: you can rent a spot at Parking Mercado del Puerto - about €15 per day or €110 per month.
