import React, {Component} from 'react';
import {connect} from 'react-redux';
import {Map, Marker, GoogleApiWrapper} from 'google-maps-react';

class EventMap extends Component {
	constructor() {
		super();
		this.styles = [
			{
				featureType: "all",
				elementType: "all",
				stylers: [
					{saturation: -100}
				],
			}
		];
		this.dimensions = {
			width: '421px',
			height: '398px'
		};
	}

	render() {
		return (<div className="events-map">
			<Map google={this.props.google}
				 zoom={3}
				 styles={this.styles}
				 style={this.dimensions}
				 disableDefaultUI={true}>
				<Marker	/>
			</Map>
		</div>);
	}
}

export default connect()(GoogleApiWrapper({
	apiKey: (GMAPS_KEY)
})(EventMap));

<Map google={this.props.google} zoom={3} styles={this.styles} style={this.dimensions} disableDefaultUI={true} clickableIcons={true}>
				<Marker	/>
			</Map>

worked for me.
