Use leaflet with bootstrap without the layer control looking horrible.

leaflet.bootstrap.js

L.Control.Layers.prototype._addItem= function (obj) {
      var label = document.createElement('label'),
		    input,
		    checked = this._map.hasLayer(obj.layer);

		if (obj.overlay) {
			input = document.createElement('input');
			input.type = 'checkbox';
			input.className = 'leaflet-control-layers-selector';
			input.defaultChecked = checked;
		} else {
			input = this._createRadioElement('leaflet-base-layers', checked);
		}

		input.layerId = L.stamp(obj.layer);

		L.DomEvent.on(input, 'click', this._onInputClick, this);

		var name = document.createElement('span');
		name.innerHTML = ' ' + obj.name;

		label.appendChild(input);
		label.appendChild(name);
		label.className = obj.overlay ? "checkbox" : "radio";
		var container = obj.overlay ? this._overlaysList : this._baseLayersList;
		container.appendChild(label);

		return label;
	}
